To determine if 528 is a prime number or a composite number, we simply look at the factors for 528.
If the factors of 528 are only 528 and 1, then we know that 528 is a prime number. Otherwise, 528 is a composite number.
To explain better, if 528 is only divisible by 1 and 528, then it is a prime number, and if 528 is divisible by more than 528 and 1, then it is a composite number.
The factors of 528 are as follows:
1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
Therefore, since 528 is divisible by more than one and itself, the answer to the
question "Is 528 prime or composite?" is highlighted in blue below.
composite
Is 529 prime or composite?
OK. Now you know that 528 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.
