To determine if 2289 is a prime number or a composite number, we simply look at the factors for 2289.
If the factors of 2289 are only 2289 and 1, then we know that 2289 is a prime number. Otherwise, 2289 is a composite number.
To explain better, if 2289 is only divisible by 1 and 2289, then it is a prime number, and if 2289 is divisible by more than 2289 and 1, then it is a composite number.
The factors of 2289 are as follows:
1, 3, 7, 21, 109, 327, 763, 2289
