To determine if 388 is a prime number or a composite number, we simply look at the factors for 388.
If the factors of 388 are only 388 and 1, then we know that 388 is a prime number. Otherwise, 388 is a composite number.
To explain better, if 388 is only divisible by 1 and 388, then it is a prime number, and if 388 is divisible by more than 388 and 1, then it is a composite number.
The factors of 388 are as follows:
1, 2, 4, 97, 194, 388
Therefore, since 388 is divisible by more than one and itself, the answer to the
question "Is 388 prime or composite?" is highlighted in blue below.
composite
Is 389 prime or composite?
