To determine if 396 is a prime number or a composite number, we simply look at the factors for 396.
If the factors of 396 are only 396 and 1, then we know that 396 is a prime number. Otherwise, 396 is a composite number.
To explain better, if 396 is only divisible by 1 and 396, then it is a prime number, and if 396 is divisible by more than 396 and 1, then it is a composite number.
The factors of 396 are as follows:
1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
Therefore, since 396 is divisible by more than one and itself, the answer to the
question "Is 396 prime or composite?" is highlighted in blue below.
composite
Is 397 prime or composite?
OK. Now you know that 396 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.
