To determine if 2542 is a prime number or a composite number, we simply look at the factors for 2542.
If the factors of 2542 are only 2542 and 1, then we know that 2542 is a prime number. Otherwise, 2542 is a composite number.
To explain better, if 2542 is only divisible by 1 and 2542, then it is a prime number, and if 2542 is divisible by more than 2542 and 1, then it is a composite number.
The factors of 2542 are as follows:
1, 2, 31, 41, 62, 82, 1271, 2542
Therefore, since 2542 is divisible by more than one and itself, the answer to the
question "Is 2542 prime or composite?" is highlighted in blue below.
