To determine if 790 is a prime number or a composite number, we simply look at the factors for 790.
If the factors of 790 are only 790 and 1, then we know that 790 is a prime number. Otherwise, 790 is a composite number.
To explain better, if 790 is only divisible by 1 and 790, then it is a prime number, and if 790 is divisible by more than 790 and 1, then it is a composite number.
The factors of 790 are as follows:
1, 2, 5, 10, 79, 158, 395, 790
Therefore, since 790 is divisible by more than one and itself, the answer to the
question "Is 790 prime or composite?" is highlighted in blue below.
composite
Is 791 prime or composite?
