To determine if 579 is a prime number or a composite number, we simply look at the factors for 579.
If the factors of 579 are only 579 and 1, then we know that 579 is a prime number. Otherwise, 579 is a composite number.
To explain better, if 579 is only divisible by 1 and 579, then it is a prime number, and if 579 is divisible by more than 579 and 1, then it is a composite number.
The factors of 579 are as follows:
1, 3, 193, 579
Therefore, since 579 is divisible by more than one and itself, the answer to the
question "Is 579 prime or composite?" is highlighted in blue below.
composite
Is 580 prime or composite?
