To determine if 2189 is a prime number or a composite number, we simply look at the factors for 2189.
If the factors of 2189 are only 2189 and 1, then we know that 2189 is a prime number. Otherwise, 2189 is a composite number.
To explain better, if 2189 is only divisible by 1 and 2189, then it is a prime number, and if 2189 is divisible by more than 2189 and 1, then it is a composite number.
The factors of 2189 are as follows:
