To determine if 2245 is a prime number or a composite number, we simply look at the factors for 2245.
If the factors of 2245 are only 2245 and 1, then we know that 2245 is a prime number. Otherwise, 2245 is a composite number.
To explain better, if 2245 is only divisible by 1 and 2245, then it is a prime number, and if 2245 is divisible by more than 2245 and 1, then it is a composite number.
The factors of 2245 are as follows:
