To determine if 512 is a prime number or a composite number, we simply look at the factors for 512.
If the factors of 512 are only 512 and 1, then we know that 512 is a prime number. Otherwise, 512 is a composite number.
To explain better, if 512 is only divisible by 1 and 512, then it is a prime number, and if 512 is divisible by more than 512 and 1, then it is a composite number.
The factors of 512 are as follows:
1, 2, 4, 8, 16, 32, 64, 128, 256, 512
Therefore, since 512 is divisible by more than one and itself, the answer to the
question "Is 512 prime or composite?" is highlighted in blue below.
composite
Is 513 prime or composite?
OK. Now you know that 512 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.
