To determine if 2515 is a prime number or a composite number, we simply look at the factors for 2515.
If the factors of 2515 are only 2515 and 1, then we know that 2515 is a prime number. Otherwise, 2515 is a composite number.
To explain better, if 2515 is only divisible by 1 and 2515, then it is a prime number, and if 2515 is divisible by more than 2515 and 1, then it is a composite number.
The factors of 2515 are as follows:
1, 5, 503, 2515
Therefore, since 2515 is divisible by more than one and itself, the answer to the
question "Is 2515 prime or composite?" is highlighted in blue below.
composite
Is 2516 prime or composite?
