Prime Factorization of 165

What is the Prime Factorization of 165?

Answer: Prime Factors of 165: 3, 5, 11

Explanation of number 165 Prime Factorization

Prime Factorization of 165 it is expressing 165 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 165.

Since number 165 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 165, we have to iteratively divide 165 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 165:

The smallest Prime Number which can divide 165 without a remainder is 3. So the first calculation step would look like:

165 ÷ 3 = 55

Now we repeat this action until the result equals 1:

55 ÷ 5 = 11

11 ÷ 11 = 1

Now we have all the Prime Factors for number 165. It is: 3, 5, 11
