Explanation of number 90 Prime Factorization

Prime Factorization of 90 it is expressing 90 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 90.

Since number 90 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 90, we have to iteratively divide 90 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 90:

The smallest Prime Number which can divide 90 without a remainder is 2. So the first calculation step would look like:

90 ÷ 2 = 45

Now we repeat this action until the result equals 1:

45 ÷ 3 = 15

15 ÷ 3 = 5

5 ÷ 5 = 1

Now we have all the Prime Factors for number 90. It is: 2, 3, 3, 5

Or you may also write it in exponential form: 2 × 32 × 5
