To determine if 2600 is a prime number or a composite number, we simply look at the factors for 2600.
If the factors of 2600 are only 2600 and 1, then we know that 2600 is a prime number. Otherwise, 2600 is a composite number.
To explain better, if 2600 is only divisible by 1 and 2600, then it is a prime number, and if 2600 is divisible by more than 2600 and 1, then it is a composite number.
The factors of 2600 are as follows:
1, 2, 4, 5, 8, 10, 13, 20, 25, 26, 40, 50, 52, 65, 100, 104, 130, 200, 260, 325, 520, 650, 1300, 2600
Therefore, since 2600 is divisible by more than one and itself, the answer to the
question "Is 2600 prime or composite?" is highlighted in blue below.
composite
Is 2601 prime or composite?
OK. Now you know that 2600 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.
