What is the Prime Factorization of 665?
Answer: Prime Factors of 665: 5, 7, 19
Explanation of number 665 Prime Factorization
Prime Factorization of 665 it is expressing 665 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 665.
Since number 665 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 665, we have to iteratively divide 665 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 665:
The smallest Prime Number which can divide 665 without a remainder is 5. So the first calculation step would look like:
665 ÷ 5 = 133
Now we repeat this action until the result equals 1:
133 ÷ 7 = 19
19 ÷ 19 = 1
Now we have all the Prime Factors for number 665. It is: 5, 7, 19
