What are the Factors of 72?

First thing first, a Factor is a Number that divides a Number at one go without producing any remainder. For example, if we multiply 2 with 3, the result will be 6. So if we divide 6 by 3 we will get 2 and if we divide 6 by 3 we will get 2. This means that 2 and 3 are the Factors of 6. Now, what are the Factors of 72? Well, Factors of 72 are the Numbers that when multiplied together in a pair of two return the result as 72. Therefore, 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72 are the Factors of 72.

Pair Factors of 72

Pair Factors are the combinations of any two Factors that are multiplied together to give 72 as the product. Here we can see all the Positive pair Factors of 72. 

1 \[\times\] 72 = 72

therefore, 1 and 72 are a Factor pair of 72 

2 \[\times\] 36 = 72

therefore, 2 and 36 are a Factor pair of 72 

3 \[\times\] 24 = 72

therefore, 3 and 24 are a Factor pair of 72 

4 \[\times\] 18 = 72

therefore, 4 and 18 are a Factor pair of 72 

6 \[\times\] 12 = 72 

therefore, 6 and 12 are a Factor pair of 72 

8 \[\times\] 9 = 72 

therefore, 8 and 9 are a Factor pair of 72 

9 \[\times\] 8 = 72

therefore, 9 and 8 are a Factor pair of 72 

12 \[\times\] 6 = 72 

therefore, 12 and 6 are a Factor pair of 72 

18 \[\times\] 4 = 72 

therefore, 18 and 4 are a Factor pair of 72 

24 \[\times\] 3 = 72 

therefore, 24 and 3 are a Factor pair of 72 

36 \[\times\] 2 = 72

therefore, 36 and 2 are a Factor pair of 72 

72 \[\times\] 1 = 72 

therefore, 72 and 1 are a Factor pair of 72

What are the various methods of Calculating Factors of 72?

There are two methods to calculate the Factors of 72. Both these methods are quite easy to understand. Here is a quick overview of these Factorisation methods: 

  1. Division Method: For calculating the Factors of 72 by division method, you have to use the Numbers that can divide 72 without leaving a remainder. Here are the Factors of 72 as per the division method: 

  • 72 ÷ 1 = 72

  • 72 ÷ 2 = 36

  • 72 ÷ 3 = 24

  • 72 ÷ 4 = 18

  • 72 ÷ 6 = 12

  • 72 ÷ 8 = 9

  • 72 ÷ 9 = 8

  • 72 ÷ 12 = 6

  • 72 ÷ 18 = 4

  • 72 ÷ 24 = 3

  • 72 ÷ 36 = 2

  • 72 ÷ 72 = 1

  1. Prime Factorisation Method: In this method, you have to express 72 as a product of its prime Factors. Start by dividing 72 with the smallest prime Number i.e. 2, which gives you 36. Then divide 72 by 3 to obtain 36. And keep doing so until you receive 1 as your quotient. So the prime Factors of 72 are  2 \[\times\] 2 \[\times\] 2 \[\times\] 3 \[\times\] 3.

FAQs on Factors of 72

1. What is the Difference Between a Factor, a Prime Factor, and a Multiple?

A Factor is a Number that we can further break down. It is all the Numbers that can be multiplied to give the original Number, but a prime Factor cannot be broken down.

For example, the Factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. But the prime Factors of 30 are 2, 3, and 5. 

Now, coming to Factors and multiples, they are very different from each other yet it is very confusing to remember what is what?!! Well, let us clarify it now, a Factor is an exact divisor of a Number whereas a multiple is the result we get after the multiplication is done.
