Explanation of number 256 Prime Factorization

Prime Factorization of 256 it is expressing 256 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 256.

Since number 256 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 256, we have to iteratively divide 256 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 256:

The smallest Prime Number which can divide 256 without a remainder is 2. So the first calculation step would look like:

256 ÷ 2 = 128

Now we repeat this action until the result equals 1:

128 ÷ 2 = 64

64 ÷ 2 = 32

32 ÷ 2 = 16

16 ÷ 2 = 8

8 ÷ 2 = 4

4 ÷ 2 = 2

2 ÷ 2 = 1

Now we have all the Prime Factors for number 256. It is: 2, 2, 2, 2, 2, 2, 2, 2

Or you may also write it in exponential form: 28
