To determine if 199 is a prime number or a composite number, we simply look at the factors for 199.
If the factors of 199 are only 199 and 1, then we know that 199 is a prime number. Otherwise, 199 is a composite number.
To explain better, if 199 is only divisible by 1 and 199, then it is a prime number, and if 199 is divisible by more than 199 and 1, then it is a composite number.
The factors of 199 are as follows:
