To determine if 2512 is a prime number or a composite number, we simply look at the factors for 2512.
If the factors of 2512 are only 2512 and 1, then we know that 2512 is a prime number. Otherwise, 2512 is a composite number.
To explain better, if 2512 is only divisible by 1 and 2512, then it is a prime number, and if 2512 is divisible by more than 2512 and 1, then it is a composite number.
The factors of 2512 are as follows:
1, 2, 4, 8, 16, 157, 314, 628, 1256, 2512
Therefore, since 2512 is divisible by more than one and itself, the answer to the
question "Is 2512 prime or composite?" is highlighted in blue below.
composite
Is 2513 prime or composite?
