To determine if 7790 is a prime number or a composite number, we simply look at the factors for 7790.
If the factors of 7790 are only 7790 and 1, then we know that 7790 is a prime number. Otherwise, 7790 is a composite number.
To explain better, if 7790 is only divisible by 1 and 7790, then it is a prime number, and if 7790 is divisible by more than 7790 and 1, then it is a composite number.
The factors of 7790 are as follows:
1, 2, 5, 10, 19, 38, 41, 82, 95, 190, 205, 410, 779, 1558, 3895, 7790
Therefore, since 7790 is divisible by more than one and itself, the answer to the
question "Is 7790 prime or composite?" is highlighted in blue below.
