To determine if 749 is a prime number or a composite number, we simply look at the factors for 749.
If the factors of 749 are only 749 and 1, then we know that 749 is a prime number. Otherwise, 749 is a composite number.
To explain better, if 749 is only divisible by 1 and 749, then it is a prime number, and if 749 is divisible by more than 749 and 1, then it is a composite number.
The factors of 749 are as follows:
1, 7, 107, 749
Therefore, since 749 is divisible by more than one and itself, the answer to the
question "Is 749 prime or composite?" is highlighted in blue below.
composite
Is 750 prime or composite?
