To determine if 9790 is a prime number or a composite number, we simply look at the factors for 9790.
If the factors of 9790 are only 9790 and 1, then we know that 9790 is a prime number. Otherwise, 9790 is a composite number.
To explain better, if 9790 is only divisible by 1 and 9790, then it is a prime number, and if 9790 is divisible by more than 9790 and 1, then it is a composite number.
The factors of 9790 are as follows:
1, 2, 5, 10, 11, 22, 55, 89, 110, 178, 445, 890, 979, 1958, 4895, 9790
Therefore, since 9790 is divisible by more than one and itself, the answer to the
question "Is 9790 prime or composite?" is highlighted in blue below.
composite
Is 9791 prime or composite?
