To determine if 8560 is a prime number or a composite number, we simply look at the factors for 8560.
If the factors of 8560 are only 8560 and 1, then we know that 8560 is a prime number. Otherwise, 8560 is a composite number.
To explain better, if 8560 is only divisible by 1 and 8560, then it is a prime number, and if 8560 is divisible by more than 8560 and 1, then it is a composite number.
The factors of 8560 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 107, 214, 428, 535, 856, 1070, 1712, 2140, 4280, 8560
Therefore, since 8560 is divisible by more than one and itself, the answer to the
question "Is 8560 prime or composite?" is highlighted in blue below.
composite
Is 8561 prime or composite?
