To determine if 3615 is a prime number or a composite number, we simply look at the factors for 3615.
If the factors of 3615 are only 3615 and 1, then we know that 3615 is a prime number. Otherwise, 3615 is a composite number.
To explain better, if 3615 is only divisible by 1 and 3615, then it is a prime number, and if 3615 is divisible by more than 3615 and 1, then it is a composite number.
The factors of 3615 are as follows:
1, 3, 5, 15, 241, 723, 1205, 3615
Therefore, since 3615 is divisible by more than one and itself, the answer to the
question "Is 3615 prime or composite?" is highlighted in blue below.
