To determine if 8730 is a prime number or a composite number, we simply look at the factors for 8730.
If the factors of 8730 are only 8730 and 1, then we know that 8730 is a prime number. Otherwise, 8730 is a composite number.
To explain better, if 8730 is only divisible by 1 and 8730, then it is a prime number, and if 8730 is divisible by more than 8730 and 1, then it is a composite number.
The factors of 8730 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90, 97, 194, 291, 485, 582, 873, 970, 1455, 1746, 2910, 4365, 8730
Therefore, since 8730 is divisible by more than one and itself, the answer to the
question "Is 8730 prime or composite?" is highlighted in blue below.
composite
Is 8731 prime or composite?
