To determine if 1797 is a prime number or a composite number, we simply look at the factors for 1797.
If the factors of 1797 are only 1797 and 1, then we know that 1797 is a prime number. Otherwise, 1797 is a composite number.
To explain better, if 1797 is only divisible by 1 and 1797, then it is a prime number, and if 1797 is divisible by more than 1797 and 1, then it is a composite number.
The factors of 1797 are as follows:
