To determine if 1791 is a prime number or a composite number, we simply look at the factors for 1791.
If the factors of 1791 are only 1791 and 1, then we know that 1791 is a prime number. Otherwise, 1791 is a composite number.
To explain better, if 1791 is only divisible by 1 and 1791, then it is a prime number, and if 1791 is divisible by more than 1791 and 1, then it is a composite number.
The factors of 1791 are as follows:
1, 3, 9, 199, 597, 1791
Therefore, since 1791 is divisible by more than one and itself, the answer to the
question "Is 1791 prime or composite?" is highlighted in blue below.
composite
Is 1792 prime or composite?
