To determine if 2680 is a prime number or a composite number, we simply look at the factors for 2680.
If the factors of 2680 are only 2680 and 1, then we know that 2680 is a prime number. Otherwise, 2680 is a composite number.
To explain better, if 2680 is only divisible by 1 and 2680, then it is a prime number, and if 2680 is divisible by more than 2680 and 1, then it is a composite number.
The factors of 2680 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 67, 134, 268, 335, 536, 670, 1340, 2680
Therefore, since 2680 is divisible by more than one and itself, the answer to the
question "Is 2680 prime or composite?" is highlighted in blue below.
composite
Is 2681 prime or composite?
OK. Now you know that 2680 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
