To determine if 6560 is a prime number or a composite number, we simply look at the factors for 6560.
If the factors of 6560 are only 6560 and 1, then we know that 6560 is a prime number. Otherwise, 6560 is a composite number.
To explain better, if 6560 is only divisible by 1 and 6560, then it is a prime number, and if 6560 is divisible by more than 6560 and 1, then it is a composite number.
The factors of 6560 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 41, 80, 82, 160, 164, 205, 328, 410, 656, 820, 1312, 1640, 3280, 6560
Therefore, since 6560 is divisible by more than one and itself, the answer to the
question "Is 6560 prime or composite?" is highlighted in blue below.
composite
Is 6561 prime or composite?
