To determine if 527 is a prime number or a composite number, we simply look at the factors for 527.
If the factors of 527 are only 527 and 1, then we know that 527 is a prime number. Otherwise, 527 is a composite number.
To explain better, if 527 is only divisible by 1 and 527, then it is a prime number, and if 527 is divisible by more than 527 and 1, then it is a composite number.
The factors of 527 are as follows:
1, 17, 31, 527
Therefore, since 527 is divisible by more than one and itself, the answer to the
question "Is 527 prime or composite?" is highlighted in blue below.
composite
Is 528 prime or composite?
OK. Now you know that 527 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.
