To determine if 392 is a prime number or a composite number, we simply look at the factors for 392.
If the factors of 392 are only 392 and 1, then we know that 392 is a prime number. Otherwise, 392 is a composite number.
To explain better, if 392 is only divisible by 1 and 392, then it is a prime number, and if 392 is divisible by more than 392 and 1, then it is a composite number.
The factors of 392 are as follows:
1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
Therefore, since 392 is divisible by more than one and itself, the answer to the
question "Is 392 prime or composite?" is highlighted in blue below.
composite
Is 393 prime or composite?
