Explanation of number 945 Prime Factorization

Prime Factorization of 945 it is expressing 945 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 945.

Since number 945 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 945, we have to iteratively divide 945 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 945:

The smallest Prime Number which can divide 945 without a remainder is 3. So the first calculation step would look like:

945 ÷ 3 = 315

Now we repeat this action until the result equals 1:

315 ÷ 3 = 105

105 ÷ 3 = 35

35 ÷ 5 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 945. It is: 3, 3, 3, 5, 7

Or you may also write it in exponential form: 33 × 5 × 7
