To determine if 2871 is a prime number or a composite number, we simply look at the factors for 2871.
If the factors of 2871 are only 2871 and 1, then we know that 2871 is a prime number. Otherwise, 2871 is a composite number.
To explain better, if 2871 is only divisible by 1 and 2871, then it is a prime number, and if 2871 is divisible by more than 2871 and 1, then it is a composite number.
The factors of 2871 are as follows:
1, 3, 9, 11, 29, 33, 87, 99, 261, 319, 957, 2871
Therefore, since 2871 is divisible by more than one and itself, the answer to the
question "Is 2871 prime or composite?" is highlighted in blue below.
composite
Is 2872 prime or composite?
