To determine if 317 is a prime number or a composite number, we simply look at the factors for 317.
If the factors of 317 are only 317 and 1, then we know that 317 is a prime number. Otherwise, 317 is a composite number.
To explain better, if 317 is only divisible by 1 and 317, then it is a prime number, and if 317 is divisible by more than 317 and 1, then it is a composite number.
The factors of 317 are as follows:
