To determine if 747 is a prime number or a composite number, we simply look at the factors for 747.
If the factors of 747 are only 747 and 1, then we know that 747 is a prime number. Otherwise, 747 is a composite number.
To explain better, if 747 is only divisible by 1 and 747, then it is a prime number, and if 747 is divisible by more than 747 and 1, then it is a composite number.
The factors of 747 are as follows:
1, 3, 9, 83, 249, 747
Therefore, since 747 is divisible by more than one and itself, the answer to the
question "Is 747 prime or composite?" is highlighted in blue below.
composite
Is 748 prime or composite?
