To determine if 8470 is a prime number or a composite number, we simply look at the factors for 8470.
If the factors of 8470 are only 8470 and 1, then we know that 8470 is a prime number. Otherwise, 8470 is a composite number.
To explain better, if 8470 is only divisible by 1 and 8470, then it is a prime number, and if 8470 is divisible by more than 8470 and 1, then it is a composite number.
The factors of 8470 are as follows:
1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 121, 154, 242, 385, 605, 770, 847, 1210, 1694, 4235, 8470
Therefore, since 8470 is divisible by more than one and itself, the answer to the
question "Is 8470 prime or composite?" is highlighted in blue below.
