To determine if 2577 is a prime number or a composite number, we simply look at the factors for 2577.
If the factors of 2577 are only 2577 and 1, then we know that 2577 is a prime number. Otherwise, 2577 is a composite number.
To explain better, if 2577 is only divisible by 1 and 2577, then it is a prime number, and if 2577 is divisible by more than 2577 and 1, then it is a composite number.
The factors of 2577 are as follows:
