Explanation of number 400 Prime Factorization

Prime Factorization of 400 it is expressing 400 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 400.

Since number 400 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 400, we have to iteratively divide 400 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 400:

The smallest Prime Number which can divide 400 without a remainder is 2. So the first calculation step would look like:

400 ÷ 2 = 200

Now we repeat this action until the result equals 1:

200 ÷ 2 = 100

100 ÷ 2 = 50

50 ÷ 2 = 25

25 ÷ 5 = 5

5 ÷ 5 = 1

Now we have all the Prime Factors for number 400. It is: 2, 2, 2, 2, 5, 5

Or you may also write it in exponential form: 24 × 52
