To determine if 8600 is a prime number or a composite number, we simply look at the factors for 8600.
If the factors of 8600 are only 8600 and 1, then we know that 8600 is a prime number. Otherwise, 8600 is a composite number.
To explain better, if 8600 is only divisible by 1 and 8600, then it is a prime number, and if 8600 is divisible by more than 8600 and 1, then it is a composite number.
The factors of 8600 are as follows:
1, 2, 4, 5, 8, 10, 20, 25, 40, 43, 50, 86, 100, 172, 200, 215, 344, 430, 860, 1075, 1720, 2150, 4300, 8600
Therefore, since 8600 is divisible by more than one and itself, the answer to the
question "Is 8600 prime or composite?" is highlighted in blue below.
composite
Is 8601 prime or composite?
