To determine if 636 is a prime number or a composite number, we simply look at the factors for 636.
If the factors of 636 are only 636 and 1, then we know that 636 is a prime number. Otherwise, 636 is a composite number.
To explain better, if 636 is only divisible by 1 and 636, then it is a prime number, and if 636 is divisible by more than 636 and 1, then it is a composite number.
The factors of 636 are as follows:
1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
Therefore, since 636 is divisible by more than one and itself, the answer to the
question "Is 636 prime or composite?" is highlighted in blue below.
composite
Is 637 prime or composite?
OK. Now you know that 636 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.
