To determine if 745 is a prime number or a composite number, we simply look at the factors for 745.
If the factors of 745 are only 745 and 1, then we know that 745 is a prime number. Otherwise, 745 is a composite number.
To explain better, if 745 is only divisible by 1 and 745, then it is a prime number, and if 745 is divisible by more than 745 and 1, then it is a composite number.
The factors of 745 are as follows:
1, 5, 149, 745
Therefore, since 745 is divisible by more than one and itself, the answer to the
question "Is 745 prime or composite?" is highlighted in blue below.
composite
Is 746 prime or composite?
