To determine if 330 is a prime number or a composite number, we simply look at the factors for 330.
If the factors of 330 are only 330 and 1, then we know that 330 is a prime number. Otherwise, 330 is a composite number.
To explain better, if 330 is only divisible by 1 and 330, then it is a prime number, and if 330 is divisible by more than 330 and 1, then it is a composite number.
The factors of 330 are as follows:
1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
Therefore, since 330 is divisible by more than one and itself, the answer to the
question "Is 330 prime or composite?" is highlighted in blue below.
composite
Is 331 prime or composite?
OK. Now you know that 330 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.
