Explanation of number 315 Prime Factorization

Prime Factorization of 315 is expressing 315 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 315.

Since number 315 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 315, we have to iteratively divide 315 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 315:

The smallest Prime Number which can divide 315 without a remainder is 3. So the first calculation step would look like:

315 ÷ 3 = 105

Now we repeat this action until the result equals 1:

105 ÷ 3 = 35

35 ÷ 5 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 315. It is: 3, 3, 5, 7

Or you may also write it in exponential form: 32 × 5 × 7
