To determine if 7998 is a prime number or a composite number, we simply look at the factors for 7998.
If the factors of 7998 are only 7998 and 1, then we know that 7998 is a prime number. Otherwise, 7998 is a composite number.
To explain better, if 7998 is only divisible by 1 and 7998, then it is a prime number, and if 7998 is divisible by more than 7998 and 1, then it is a composite number.
The factors of 7998 are as follows:
