To determine if 477 is a prime number or a composite number, we simply look at the factors for 477.
If the factors of 477 are only 477 and 1, then we know that 477 is a prime number. Otherwise, 477 is a composite number.
To explain better, if 477 is only divisible by 1 and 477, then it is a prime number, and if 477 is divisible by more than 477 and 1, then it is a composite number.
The factors of 477 are as follows:
1, 3, 9, 53, 159, 477
Therefore, since 477 is divisible by more than one and itself, the answer to the
question "Is 477 prime or composite?" is highlighted in blue below.
composite
Is 478 prime or composite?
OK. Now you know that 477 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.
