To determine if 1799 is a prime number or a composite number, we simply look at the factors for 1799.
If the factors of 1799 are only 1799 and 1, then we know that 1799 is a prime number. Otherwise, 1799 is a composite number.
To explain better, if 1799 is only divisible by 1 and 1799, then it is a prime number, and if 1799 is divisible by more than 1799 and 1, then it is a composite number.
The factors of 1799 are as follows:
