Is 170 prime or composite?


To determine if 170 is a prime number or a composite number, we simply look at the factors for 170.

If the factors of 170 are only 170 and 1, then we know that 170 is a prime number. Otherwise, 170 is a composite number.

To explain better, if 170 is only divisible by 1 and 170, then it is a prime number, and if 170 is divisible by more than 170 and 1, then it is a composite number.

The factors of 170 are as follows:
