To determine if 2538 is a prime number or a composite number, we simply look at the factors for 2538.
If the factors of 2538 are only 2538 and 1, then we know that 2538 is a prime number. Otherwise, 2538 is a composite number.
To explain better, if 2538 is only divisible by 1 and 2538, then it is a prime number, and if 2538 is divisible by more than 2538 and 1, then it is a composite number.
The factors of 2538 are as follows:
1, 2, 3, 6, 9, 18, 27, 47, 54, 94, 141, 282, 423, 846, 1269, 2538
Therefore, since 2538 is divisible by more than one and itself, the answer to the
question "Is 2538 prime or composite?" is highlighted in blue below.
composite
Is 2539 prime or composite?
