To determine if 8715 is a prime number or a composite number, we simply look at the factors for 8715.
If the factors of 8715 are only 8715 and 1, then we know that 8715 is a prime number. Otherwise, 8715 is a composite number.
To explain better, if 8715 is only divisible by 1 and 8715, then it is a prime number, and if 8715 is divisible by more than 8715 and 1, then it is a composite number.
The factors of 8715 are as follows:
1, 3, 5, 7, 15, 21, 35, 83, 105, 249, 415, 581, 1245, 1743, 2905, 8715
Therefore, since 8715 is divisible by more than one and itself, the answer to the
question "Is 8715 prime or composite?" is highlighted in blue below.
composite
Is 8716 prime or composite?
