To determine if 516 is a prime number or a composite number, we simply look at the factors for 516.
If the factors of 516 are only 516 and 1, then we know that 516 is a prime number. Otherwise, 516 is a composite number.
To explain better, if 516 is only divisible by 1 and 516, then it is a prime number, and if 516 is divisible by more than 516 and 1, then it is a composite number.
The factors of 516 are as follows:
1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
Therefore, since 516 is divisible by more than one and itself, the answer to the
question "Is 516 prime or composite?" is highlighted in blue below.
composite
Is 517 prime or composite?
OK. Now you know that 516 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.
