To determine if 9315 is a prime number or a composite number, we simply look at the factors for 9315.
If the factors of 9315 are only 9315 and 1, then we know that 9315 is a prime number. Otherwise, 9315 is a composite number.
To explain better, if 9315 is only divisible by 1 and 9315, then it is a prime number, and if 9315 is divisible by more than 9315 and 1, then it is a composite number.
The factors of 9315 are as follows:
1, 3, 5, 9, 15, 23, 27, 45, 69, 81, 115, 135, 207, 345, 405, 621, 1035, 1863, 3105, 9315
Therefore, since 9315 is divisible by more than one and itself, the answer to the
question "Is 9315 prime or composite?" is highlighted in blue below.
