To determine if 2177 is a prime number or a composite number, we simply look at the factors for 2177.
If the factors of 2177 are only 2177 and 1, then we know that 2177 is a prime number. Otherwise, 2177 is a composite number.
To explain better, if 2177 is only divisible by 1 and 2177, then it is a prime number, and if 2177 is divisible by more than 2177 and 1, then it is a composite number.
The factors of 2177 are as follows:
