To determine if 7311 is a prime number or a composite number, we simply look at the factors for 7311.
If the factors of 7311 are only 7311 and 1, then we know that 7311 is a prime number. Otherwise, 7311 is a composite number.
To explain better, if 7311 is only divisible by 1 and 7311, then it is a prime number, and if 7311 is divisible by more than 7311 and 1, then it is a composite number.
The factors of 7311 are as follows:
1, 3, 2437, 7311
Therefore, since 7311 is divisible by more than one and itself, the answer to the
question "Is 7311 prime or composite?" is highlighted in blue below.
composite
Is 7312 prime or composite?
