To determine if 2511 is a prime number or a composite number, we simply look at the factors for 2511.
If the factors of 2511 are only 2511 and 1, then we know that 2511 is a prime number. Otherwise, 2511 is a composite number.
To explain better, if 2511 is only divisible by 1 and 2511, then it is a prime number, and if 2511 is divisible by more than 2511 and 1, then it is a composite number.
The factors of 2511 are as follows:
1, 3, 9, 27, 31, 81, 93, 279, 837, 2511
Therefore, since 2511 is divisible by more than one and itself, the answer to the
question "Is 2511 prime or composite?" is highlighted in blue below.
composite
Is 2512 prime or composite?
