To determine if 575 is a prime number or a composite number, we simply look at the factors for 575.
If the factors of 575 are only 575 and 1, then we know that 575 is a prime number. Otherwise, 575 is a composite number.
To explain better, if 575 is only divisible by 1 and 575, then it is a prime number, and if 575 is divisible by more than 575 and 1, then it is a composite number.
The factors of 575 are as follows:
1, 5, 23, 25, 115, 575
Therefore, since 575 is divisible by more than one and itself, the answer to the
question "Is 575 prime or composite?" is highlighted in blue below.
composite
Is 576 prime or composite?
OK. Now you know that 575 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
