What are the Factors of 18?

Factors of 18 are the list of integers that are divided by the original number 18 without leaving a remainder. There are six factors of 18, having 1 as the smallest and 18 as the biggest factor. The factors of 18 are 1, 2, 3, 6, 9, and 18, and the pair of factors of 18 are (1, 18), (2, 9) and (3, 6). The sum of total factors of 18 is 39. The number 18 is a composite number and has more factors apart from one and itself. Kids need to understand the importance of learning factors of 18 to solve multiplication and division related problems. Check out the ways to calculate factors of 18 by the following methods given below.

How to Calculate the Factors of 18

To calculate factors of 18, you can use division or multiplication methods. Factors of 18 are the whole numbers, and these integers are never a fraction or a decimal number. Factors of 18 have both positive and negative factors. Kids in elementary school are introduced to factors of 18 to help them solve mathematical problems easily. Moreover, it enables children to calculate day-to-day math problems with speed and accuracy. Check the following methods of calculating factors of 18.

18/1 = 18

18/2 = 9

18/3 = 6

18/6 =3

18/9 = 2

18/18 = 1

Therefore, 1, 2, 3, 6, 9 and 18 are factors of 18. 

Pair Factors of 18 

The pair factors of 18 are the numbers multiplied together to give the product number 18. Check out the methods used to calculate the pair factors of 18 given below. 

1 x 18 = 18

3 x 6 = 18

2 x 9 = 18 

Therefore, the pair factors of 18 are (1, 18), (3, 6) and (2, 9). Also, explore the 18 times table to solve multiplication related problems. 

Negative Factors of 18 

Factors of 18 also include negative factors. You can multiply two negative factors together to give a positive number factor of 18. 

-1 x -18 = 18

-3 x -6 = 18

-2 x -9 = 18 

Therefore, the negative pair factors of 18 are (-1, -18), (-3, -6) and (-2, -9). 

Prime Factors of 18 

To calculate the prime factors of 18, you need to take the least number of factors of 18, which is two and divide by the original number, i.e. 18/2 = 9. You can continue the steps till you get the quotient 1. You can calculate the prime factors of 18 by the division method. The prime factors of 18 are 2 x 3 x 3 = 2 x 32.

Solved Examples on Factors of 18 

Some of the solved examples on factors of 18 are mentioned below:

Example 1: Samuel got 18 comic books for the school kids. He gave all the books to 9 kids. How many books did each kid get?

Solution: Number of comic books = 18 

Number of students = 9 

Total number of comic books received by each kid = 18/9 = 2

Therefore, the total number of comic books received by each kid is 2. 

Example 2: Find the common factor of 18 and 24. 

Solution: Factors of 18 = 1, 2, 3, 6, 9, and 18

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, and 24

Therefore, the common factors of 18 and 24 are 1, 2, 3, and 6. 

Example 3: A girl living in the countryside bought 18 pairs of shoes for the people of her village. She gave all the pairs of shoes to 6 people living in the village. How many pairs of shoes did each one receive?

Solution: Number of pairs of shoes = 18 

Number of people who received shoes = 6 

The total number of pairs of shoes each person received = 18/6 = 3

Therefore, the total number of pairs of shoes received by each person is 3.
