To determine if 548 is a prime number or a composite number, we simply look at the factors for 548.
If the factors of 548 are only 548 and 1, then we know that 548 is a prime number. Otherwise, 548 is a composite number.
To explain better, if 548 is only divisible by 1 and 548, then it is a prime number, and if 548 is divisible by more than 548 and 1, then it is a composite number.
The factors of 548 are as follows:
1, 2, 4, 137, 274, 548
Therefore, since 548 is divisible by more than one and itself, the answer to the
question "Is 548 prime or composite?" is highlighted in blue below.
composite
Is 549 prime or composite?
