To determine if 7315 is a prime number or a composite number, we simply look at the factors for 7315.
If the factors of 7315 are only 7315 and 1, then we know that 7315 is a prime number. Otherwise, 7315 is a composite number.
To explain better, if 7315 is only divisible by 1 and 7315, then it is a prime number, and if 7315 is divisible by more than 7315 and 1, then it is a composite number.
The factors of 7315 are as follows:
1, 5, 7, 11, 19, 35, 55, 77, 95, 133, 209, 385, 665, 1045, 1463, 7315
Therefore, since 7315 is divisible by more than one and itself, the answer to the
question "Is 7315 prime or composite?" is highlighted in blue below.
composite
Is 7316 prime or composite?
