To determine if 2517 is a prime number or a composite number, we simply look at the factors for 2517.
If the factors of 2517 are only 2517 and 1, then we know that 2517 is a prime number. Otherwise, 2517 is a composite number.
To explain better, if 2517 is only divisible by 1 and 2517, then it is a prime number, and if 2517 is divisible by more than 2517 and 1, then it is a composite number.
The factors of 2517 are as follows:
1, 3, 839, 2517
Therefore, since 2517 is divisible by more than one and itself, the answer to the
question "Is 2517 prime or composite?" is highlighted in blue below.
composite
Is 2518 prime or composite?
