To determine if 7791 is a prime number or a composite number, we simply look at the factors for 7791.
If the factors of 7791 are only 7791 and 1, then we know that 7791 is a prime number. Otherwise, 7791 is a composite number.
To explain better, if 7791 is only divisible by 1 and 7791, then it is a prime number, and if 7791 is divisible by more than 7791 and 1, then it is a composite number.
The factors of 7791 are as follows:
1, 3, 7, 21, 49, 53, 147, 159, 371, 1113, 2597, 7791
Therefore, since 7791 is divisible by more than one and itself, the answer to the
question "Is 7791 prime or composite?" is highlighted in blue below.
composite
Is 7792 prime or composite?
