To determine if 328 is a prime number or a composite number, we simply look at the factors for 328.
If the factors of 328 are only 328 and 1, then we know that 328 is a prime number. Otherwise, 328 is a composite number.
To explain better, if 328 is only divisible by 1 and 328, then it is a prime number, and if 328 is divisible by more than 328 and 1, then it is a composite number.
The factors of 328 are as follows:
1, 2, 4, 8, 41, 82, 164, 328
Therefore, since 328 is divisible by more than one and itself, the answer to the
question "Is 328 prime or composite?" is highlighted in blue below.
composite
Is 329 prime or composite?
OK. Now you know that 328 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.
