To determine if 2560 is a prime number or a composite number, we simply look at the factors for 2560.
If the factors of 2560 are only 2560 and 1, then we know that 2560 is a prime number. Otherwise, 2560 is a composite number.
To explain better, if 2560 is only divisible by 1 and 2560, then it is a prime number, and if 2560 is divisible by more than 2560 and 1, then it is a composite number.
The factors of 2560 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1280, 2560
Therefore, since 2560 is divisible by more than one and itself, the answer to the
question "Is 2560 prime or composite?" is highlighted in blue below.
composite
Is 2561 prime or composite?
OK. Now you know that 2560 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.
