How to calculate the factors of 18?
The numbers that can divide 18 without the remainder are the factors. Each integer may be divided by one and by itself.
Calculating factors of 18
18/1 | 18 gives remainder 0 and so are divisible by 1 |
---|---|
18/2 | 9 gives remainder 0 and so are divisible by 2 |
18/3 | 6 gives remainder 0 and so are divisible by 3 |
18/6 | 3 gives remainder 0 and so are divisible by 6 |
18/9 | 2 gives remainder 0 and so are divisible by 9 |
18/18 | 1 gives remainder 0 and so are divisible by 18 |
Other Integer Numbers that divides with remainder are 4, 5, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17. As they divide with the remainder, so cannot be factors of 18. Only integers and whole numbers can be converted to factors.

We acquire the factors of 18 or numbers that can multiply together to equal the converted target number by identifying the numbers that can divide 18 without leaving a residue.
-
When it comes to numbers, they can divide 18 without leaving any remainders. So we start with 1, then check 2, 3, 4, 5, 6, 7, 8, 9, and so on, up to and including 18.
-
We can identify factors by dividing 18 by the lowest integer in a value that will not leave a residue. Factors are numbers that divide without leaving any remainders.
-
Whole numbers, often known as integers, are the elements that are multiplied together to generate a specific number. The factors of the given number are whole numbers or integers multiplied. If x multiplied by y equals z, then x and y are z factors.
For example, suppose we wish to examine the factors of 20. We must assess the combination of integers that, when multiplied together, equals 20. The numbers 4 and 5 are used in this example because multiplying them yields 20. As a result, the given number (20) factors are 4 and 5.
Furthermore, 2 and 10, as well as 1 and 20, are factors of 20 because 2 x 10 = 20 and 1 x 20 = 20. As a result, the factors of the given number 20 are 1, 2, 4, 5, 10, and 20.
In mathematics, factors are similar to division in that they yield all numbers that divide evenly into a number with no residue. Number 8 is an example. It is equally divisible by 4 and 2, implying that 4 and 2 are components of the number 8.
Summary:
In considering numbers, they can divide 18 without remainders. If x multiplied by y = z, then x and y are factors of z. We can get factors by dividing 18 by numbers smallest in value to find the one that will not leave the number.
Multiples of 18
Multiples of 18 are all the numbers that can be divided by 18. These multiples leave no remainder and quotient when divided by 18, which are natural numbers.
As factors, sometimes multiples are misunderstood, which is not right. The numbers which give the original number 18 when multiplied together in pairs are known as the factors of 18.
Whereas multiples are all the numbers that could be written in the form of np, where n is the series of natural numbers and p is the number of which we need multiples.
We get the whole number when we divide the multiples of a number by the original number, Let us see some examples:
54÷18 = 3
126÷18 = 7
180 ÷ 18 = 10
Multiple of 18 is any number that can be denoted as 18n, where n is any number.
For instance, 36, 60, 180, and 10 are multiples of 18 for the following reasons.
18 | = | 18 | × | 1 |
---|---|---|---|---|
36 | = | 18 | × | 2 |
180 | = | 18 | × | 10 |
72 | = | 18 | × | 4 |
These values are obtained by subtracting or adding the original value many times, so these values are called multiples.

Frequently Asked Questions - FAQs
Here are some frequently asked questions regarding factors of 18.
1. What are the common factors between 24 and 18?
The largest common factor is the one that splits the two integers most evenly. To discover the biggest common factor, list each number’s prime factors. Two 2s and one 3 are shared by individuals aged 18 to 24. The GCF of 18 and 24 is 2 3 = 6, obtained through multiplication.
2. What are the seven aspects?
The factors 7 are 1 and 7, and the 7 are 1 and 7. Since 7 and 7 have a least common multiple of 7, and a greatest common divisor, or GCD, of 7 also equals 7, it follows that 7.
3. Which factors only include two factors?
A prime number has just two elements, one and itself; this is how it is defined.
4. What is the factor of 23?
Factors 23 are 1 and 23. 23 has only two factors because it is a prime number. Factor pairs of the number 23 are natural numbers but not a fraction or decimal numbers.
5. What is the highest common factor of 15 and 20?
The GCF number is the largest common factor number. As a result, the biggest common factor between 15 and 20 is 5.
6. What are the factors of 120?
All factors of 120 include 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.
7. What constitutes a term’s Factors?
Its components are the numbers or variables multiplied to generate the word. For instance, 5xy consists of the elements 5, x, and y. The factors cannot be factorized further. 5xy cannot be expressed as the product of the components 5 and XY.
8. What are the factors of 19?
19 is a prime number because the only factors of 19 are 1 and 19. That is, 19 is divisible by only 1 and 19, so it is prime.
9. What is the product of 36 and 54?
To obtain the HCF, we must multiply all of the common components. As a result, the largest common factor of 54 and 36 is 2313=18.
10.How are factors and multiples defined?
Multiples are the numbers you get when you multiply two numbers together.
11. What Are Factors?
A factor is defined as a number that divides another number without leaving a residue. If multiplying two whole numbers produces a product, then the numbers being multiplied are factors of the product since they are divisible by the result.
12. How can a factor be identified?
Determine the number, such as 24, whose factors you wish to discover. Find two different integers that multiply to 24. 1 x 24 equals 2 x 12 equals 3 x 8 equals 4 x 6 equals 24. It indicates that the factors of 24 are 1, 2, 3, 4, 6, 8, and 24.
13. What is the optimal amount?
A positive integer is equal to the sum of its appropriate divisors. Six, the sum of one, two, and three, is the lowest perfect number. 28, 496, and 8,128 are also perfect numbers. Prehistoric times obscure the finding of such quantities.
14. Do numbers end?
Whether counting backward or forwards, it appears like the numbers never cease.
15. How can one instruct a number’s factors?
The most effective strategy for teaching pupils to identify factor pairs is, to begin with 1 and work their way up. Give your kids a goal number and have them write “1 x” beneath it. Allow them to enter the number itself on the right side. Every integer has a “factor pair” of 1 time itself.
