To determine if 573 is a prime number or a composite number, we simply look at the factors for 573.
If the factors of 573 are only 573 and 1, then we know that 573 is a prime number. Otherwise, 573 is a composite number.
To explain better, if 573 is only divisible by 1 and 573, then it is a prime number, and if 573 is divisible by more than 573 and 1, then it is a composite number.
The factors of 573 are as follows:
1, 3, 191, 573
Therefore, since 573 is divisible by more than one and itself, the answer to the
question "Is 573 prime or composite?" is highlighted in blue below.
composite
Is 574 prime or composite?
