To determine if 319 is a prime number or a composite number, we simply look at the factors for 319.
If the factors of 319 are only 319 and 1, then we know that 319 is a prime number. Otherwise, 319 is a composite number.
To explain better, if 319 is only divisible by 1 and 319, then it is a prime number, and if 319 is divisible by more than 319 and 1, then it is a composite number.
The factors of 319 are as follows:
1, 11, 29, 319
Therefore, since 319 is divisible by more than one and itself, the answer to the
question "Is 319 prime or composite?" is highlighted in blue below.
composite
Is 320 prime or composite?
