To determine if 48 is a prime number or a composite number, we simply look at the factors for 48.
If the factors of 48 are only 48 and 1, then we know that 48 is a prime number. Otherwise, 48 is a composite number.
To explain better, if 48 is only divisible by 1 and 48, then it is a prime number, and if 48 is divisible by more than 48 and 1, then it is a composite number.
The factors of 48 are as follows:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Therefore, since 48 is divisible by more than one and itself, the answer to the
question "Is 48 prime or composite?" is highlighted in blue below.
composite
Is 49 prime or composite?
OK. Now you know that 48 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.
