Explanation of number 20 Prime Factorization

Prime Factorization of 20 is expressing 20 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 20.

Since number 20 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 20, we have to iteratively divide 20 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 20:

The smallest Prime Number which can divide 20 without a remainder is 2. So the first calculation step would look like:

20 ÷ 2 = 10

Now we repeat this action until the result equals 1:

10 ÷ 2 = 5

5 ÷ 5 = 1

Now we have all the Prime Factors for number 20. It is: 2, 2, 5

Or you may also write it in exponential form: 22 × 5
