To determine if 1798 is a prime number or a composite number, we simply look at the factors for 1798.
If the factors of 1798 are only 1798 and 1, then we know that 1798 is a prime number. Otherwise, 1798 is a composite number.
To explain better, if 1798 is only divisible by 1 and 1798, then it is a prime number, and if 1798 is divisible by more than 1798 and 1, then it is a composite number.
The factors of 1798 are as follows:
1, 2, 29, 31, 58, 62, 899, 1798
Therefore, since 1798 is divisible by more than one and itself, the answer to the
question "Is 1798 prime or composite?" is highlighted in blue below.
