To determine if 7122 is a prime number or a composite number, we simply look at the factors for 7122.
If the factors of 7122 are only 7122 and 1, then we know that 7122 is a prime number. Otherwise, 7122 is a composite number.
To explain better, if 7122 is only divisible by 1 and 7122, then it is a prime number, and if 7122 is divisible by more than 7122 and 1, then it is a composite number.
The factors of 7122 are as follows:
1, 2, 3, 6, 1187, 2374, 3561, 7122
