To determine if 504 is a prime number or a composite number, we simply look at the factors for 504.
If the factors of 504 are only 504 and 1, then we know that 504 is a prime number. Otherwise, 504 is a composite number.
To explain better, if 504 is only divisible by 1 and 504, then it is a prime number, and if 504 is divisible by more than 504 and 1, then it is a composite number.
The factors of 504 are as follows:
1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
Therefore, since 504 is divisible by more than one and itself, the answer to the
question "Is 504 prime or composite?" is highlighted in blue below.
composite
Is 505 prime or composite?
OK. Now you know that 504 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.
