Factors

Prime factors are the smaller numbers that can be multiplied together to make a bigger number.

For example, the prime factors of 12 are 2 ,2 and 3 because you can multiply 2, 2 and 3 together to get 12.

Example

Let’s say we want to find the prime factors of the number 20.

How It Works?

Step 1: Start by dividing 20 by the smallest prime number, which is 2.
20 ÷ 2 = 10

Step 2: Now, we try to divide 10 by 2 again.
10 ÷ 2 = 5

Step 2: Now, we try to divide 5 by 5 itself.
5 ÷ 5 = 1

Step 3: We can’t divide 5 any further, so the prime factors of 20 are 2 and 2 and 5.

Therefore, for 20 we have 2,  2 and 5, because when you multiply 2 by 2 and 5 together, you get 20.
