To determine if 1317 is a prime number or a composite number, we simply look at the factors for 1317.
If the factors of 1317 are only 1317 and 1, then we know that 1317 is a prime number. Otherwise, 1317 is a composite number.
To explain better, if 1317 is only divisible by 1 and 1317, then it is a prime number, and if 1317 is divisible by more than 1317 and 1, then it is a composite number.
The factors of 1317 are as follows:
1, 3, 439, 1317
Therefore, since 1317 is divisible by more than one and itself, the answer to the
question "Is 1317 prime or composite?" is highlighted in blue below.
composite
Is 1318 prime or composite?
