To determine if 316 is a prime number or a composite number, we simply look at the factors for 316.
If the factors of 316 are only 316 and 1, then we know that 316 is a prime number. Otherwise, 316 is a composite number.
To explain better, if 316 is only divisible by 1 and 316, then it is a prime number, and if 316 is divisible by more than 316 and 1, then it is a composite number.
The factors of 316 are as follows:
1, 2, 4, 79, 158, 316
Therefore, since 316 is divisible by more than one and itself, the answer to the
question "Is 316 prime or composite?" is highlighted in blue below.
composite
Is 317 prime or composite?
OK. Now you know that 316 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
