To determine if 2188 is a prime number or a composite number, we simply look at the factors for 2188.
If the factors of 2188 are only 2188 and 1, then we know that 2188 is a prime number. Otherwise, 2188 is a composite number.
To explain better, if 2188 is only divisible by 1 and 2188, then it is a prime number, and if 2188 is divisible by more than 2188 and 1, then it is a composite number.
The factors of 2188 are as follows:
