To determine if 612 is a prime number or a composite number, we simply look at the factors for 612.
If the factors of 612 are only 612 and 1, then we know that 612 is a prime number. Otherwise, 612 is a composite number.
To explain better, if 612 is only divisible by 1 and 612, then it is a prime number, and if 612 is divisible by more than 612 and 1, then it is a composite number.
The factors of 612 are as follows:
1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
Therefore, since 612 is divisible by more than one and itself, the answer to the
question "Is 612 prime or composite?" is highlighted in blue below.
composite
Is 613 prime or composite?
OK. Now you know that 612 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.
