To determine if 8315 is a prime number or a composite number, we simply look at the factors for 8315.
If the factors of 8315 are only 8315 and 1, then we know that 8315 is a prime number. Otherwise, 8315 is a composite number.
To explain better, if 8315 is only divisible by 1 and 8315, then it is a prime number, and if 8315 is divisible by more than 8315 and 1, then it is a composite number.
The factors of 8315 are as follows:
1, 5, 1663, 8315
Therefore, since 8315 is divisible by more than one and itself, the answer to the
question "Is 8315 prime or composite?" is highlighted in blue below.
