To determine if 756 is a prime number or a composite number, we simply look at the factors for 756.
If the factors of 756 are only 756 and 1, then we know that 756 is a prime number. Otherwise, 756 is a composite number.
To explain better, if 756 is only divisible by 1 and 756, then it is a prime number, and if 756 is divisible by more than 756 and 1, then it is a composite number.
The factors of 756 are as follows:
1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
Therefore, since 756 is divisible by more than one and itself, the answer to the
question "Is 756 prime or composite?" is highlighted in blue below.
composite
Is 757 prime or composite?
OK. Now you know that 756 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.
