To determine if 2390 is a prime number or a composite number, we simply look at the factors for 2390.
If the factors of 2390 are only 2390 and 1, then we know that 2390 is a prime number. Otherwise, 2390 is a composite number.
To explain better, if 2390 is only divisible by 1 and 2390, then it is a prime number, and if 2390 is divisible by more than 2390 and 1, then it is a composite number.
The factors of 2390 are as follows:
1, 2, 5, 10, 239, 478, 1195, 2390
Therefore, since 2390 is divisible by more than one and itself, the answer to the
