To determine if 2642 is a prime number or a composite number, we simply look at the factors for 2642.
If the factors of 2642 are only 2642 and 1, then we know that 2642 is a prime number. Otherwise, 2642 is a composite number.
To explain better, if 2642 is only divisible by 1 and 2642, then it is a prime number, and if 2642 is divisible by more than 2642 and 1, then it is a composite number.
The factors of 2642 are as follows:
