To determine if 8500 is a prime number or a composite number, we simply look at the factors for 8500.
If the factors of 8500 are only 8500 and 1, then we know that 8500 is a prime number. Otherwise, 8500 is a composite number.
To explain better, if 8500 is only divisible by 1 and 8500, then it is a prime number, and if 8500 is divisible by more than 8500 and 1, then it is a composite number.
The factors of 8500 are as follows:
1, 2, 4, 5, 10, 17, 20, 25, 34, 50, 68, 85, 100, 125, 170, 250, 340, 425, 500, 850, 1700, 2125, 4250, 8500
Therefore, since 8500 is divisible by more than one and itself, the answer to the
question "Is 8500 prime or composite?" is highlighted in blue below.
composite
Is 8501 prime or composite?
