To determine if 394 is a prime number or a composite number, we simply look at the factors for 394.
If the factors of 394 are only 394 and 1, then we know that 394 is a prime number. Otherwise, 394 is a composite number.
To explain better, if 394 is only divisible by 1 and 394, then it is a prime number, and if 394 is divisible by more than 394 and 1, then it is a composite number.
The factors of 394 are as follows:
1, 2, 197, 394
Therefore, since 394 is divisible by more than one and itself, the answer to the
question "Is 394 prime or composite?" is highlighted in blue below.
composite
Is 395 prime or composite?
