To determine if 312 is a prime number or a composite number, we simply look at the factors for 312.
If the factors of 312 are only 312 and 1, then we know that 312 is a prime number. Otherwise, 312 is a composite number.
To explain better, if 312 is only divisible by 1 and 312, then it is a prime number, and if 312 is divisible by more than 312 and 1, then it is a composite number.
The factors of 312 are as follows:
1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
Therefore, since 312 is divisible by more than one and itself, the answer to the
question "Is 312 prime or composite?" is highlighted in blue below.
composite
Is 313 prime or composite?
OK. Now you know that 312 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.
