To determine if 542 is a prime number or a composite number, we simply look at the factors for 542.
If the factors of 542 are only 542 and 1, then we know that 542 is a prime number. Otherwise, 542 is a composite number.
To explain better, if 542 is only divisible by 1 and 542, then it is a prime number, and if 542 is divisible by more than 542 and 1, then it is a composite number.
The factors of 542 are as follows:
1, 2, 271, 542
Therefore, since 542 is divisible by more than one and itself, the answer to the
question "Is 542 prime or composite?" is highlighted in blue below.
composite
Is 543 prime or composite?
