To determine if 54 is a prime number or a composite number, we simply look at the factors for 54.
If the factors of 54 are only 54 and 1, then we know that 54 is a prime number. Otherwise, 54 is a composite number.
To explain better, if 54 is only divisible by 1 and 54, then it is a prime number, and if 54 is divisible by more than 54 and 1, then it is a composite number.
The factors of 54 are as follows:
1, 2, 3, 6, 9, 18, 27, 54
Therefore, since 54 is divisible by more than one and itself, the answer to the
question "Is 54 prime or composite?" is highlighted in blue below.
composite
Is 55 prime or composite?
OK. Now you know that 54 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
