To determine if 3015 is a prime number or a composite number, we simply look at the factors for 3015.
If the factors of 3015 are only 3015 and 1, then we know that 3015 is a prime number. Otherwise, 3015 is a composite number.
To explain better, if 3015 is only divisible by 1 and 3015, then it is a prime number, and if 3015 is divisible by more than 3015 and 1, then it is a composite number.
The factors of 3015 are as follows:
1, 3, 5, 9, 15, 45, 67, 201, 335, 603, 1005, 3015
Therefore, since 3015 is divisible by more than one and itself, the answer to the
question "Is 3015 prime or composite?" is highlighted in blue below.
composite
Is 3016 prime or composite?
