To determine if 742 is a prime number or a composite number, we simply look at the factors for 742.
If the factors of 742 are only 742 and 1, then we know that 742 is a prime number. Otherwise, 742 is a composite number.
To explain better, if 742 is only divisible by 1 and 742, then it is a prime number, and if 742 is divisible by more than 742 and 1, then it is a composite number.
The factors of 742 are as follows:
1, 2, 7, 14, 53, 106, 371, 742
Therefore, since 742 is divisible by more than one and itself, the answer to the
question "Is 742 prime or composite?" is highlighted in blue below.
composite
Is 743 prime or composite?
