To determine if 8422 is a prime number or a composite number, we simply look at the factors for 8422.
If the factors of 8422 are only 8422 and 1, then we know that 8422 is a prime number. Otherwise, 8422 is a composite number.
To explain better, if 8422 is only divisible by 1 and 8422, then it is a prime number, and if 8422 is divisible by more than 8422 and 1, then it is a composite number.
The factors of 8422 are as follows:
