To determine if 478 is a prime number or a composite number, we simply look at the factors for 478.
If the factors of 478 are only 478 and 1, then we know that 478 is a prime number. Otherwise, 478 is a composite number.
To explain better, if 478 is only divisible by 1 and 478, then it is a prime number, and if 478 is divisible by more than 478 and 1, then it is a composite number.
The factors of 478 are as follows:
1, 2, 239, 478
Therefore, since 478 is divisible by more than one and itself, the answer to the
question "Is 478 prime or composite?" is highlighted in blue below.
composite
Is 479 prime or composite?
