To determine if 76 is a prime number or a composite number, we simply look at the factors for 76.
If the factors of 76 are only 76 and 1, then we know that 76 is a prime number. Otherwise, 76 is a composite number.
To explain better, if 76 is only divisible by 1 and 76, then it is a prime number, and if 76 is divisible by more than 76 and 1, then it is a composite number.
The factors of 76 are as follows:
1, 2, 4, 19, 38, 76
Therefore, since 76 is divisible by more than one and itself, the answer to the
question "Is 76 prime or composite?" is highlighted in blue below.
composite
Is 77 prime or composite?
OK. Now you know that 76 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.
