To determine if 510 is a prime number or a composite number, we simply look at the factors for 510.
If the factors of 510 are only 510 and 1, then we know that 510 is a prime number. Otherwise, 510 is a composite number.
To explain better, if 510 is only divisible by 1 and 510, then it is a prime number, and if 510 is divisible by more than 510 and 1, then it is a composite number.
The factors of 510 are as follows:
1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
Therefore, since 510 is divisible by more than one and itself, the answer to the
question "Is 510 prime or composite?" is highlighted in blue below.
composite
Is 511 prime or composite?
OK. Now you know that 510 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.
