Explanation of number 28 Prime Factorization

Prime Factorization of 28 it is expressing 28 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 28.

Since number 28 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 28, we have to iteratively divide 28 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 28:

The smallest Prime Number which can divide 28 without a remainder is 2. So the first calculation step would look like:

28 ÷ 2 = 14

Now we repeat this action until the result equals 1:

14 ÷ 2 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 28. It is: 2, 2, 7

Or you may also write it in exponential form: 22 × 7
