To determine if 2644 is a prime number or a composite number, we simply look at the factors for 2644.
If the factors of 2644 are only 2644 and 1, then we know that 2644 is a prime number. Otherwise, 2644 is a composite number.
To explain better, if 2644 is only divisible by 1 and 2644, then it is a prime number, and if 2644 is divisible by more than 2644 and 1, then it is a composite number.
The factors of 2644 are as follows:
