To determine if 2290 is a prime number or a composite number, we simply look at the factors for 2290.
If the factors of 2290 are only 2290 and 1, then we know that 2290 is a prime number. Otherwise, 2290 is a composite number.
To explain better, if 2290 is only divisible by 1 and 2290, then it is a prime number, and if 2290 is divisible by more than 2290 and 1, then it is a composite number.
The factors of 2290 are as follows:
1, 2, 5, 10, 229, 458, 1145, 2290
Therefore, since 2290 is divisible by more than one and itself, the answer to the
