To determine if 8570 is a prime number or a composite number, we simply look at the factors for 8570.
If the factors of 8570 are only 8570 and 1, then we know that 8570 is a prime number. Otherwise, 8570 is a composite number.
To explain better, if 8570 is only divisible by 1 and 8570, then it is a prime number, and if 8570 is divisible by more than 8570 and 1, then it is a composite number.
The factors of 8570 are as follows:
1, 2, 5, 10, 857, 1714, 4285, 8570
Therefore, since 8570 is divisible by more than one and itself, the answer to the
question "Is 8570 prime or composite?" is highlighted in blue below.
