To determine if 485 is a prime number or a composite number, we simply look at the factors for 485.
If the factors of 485 are only 485 and 1, then we know that 485 is a prime number. Otherwise, 485 is a composite number.
To explain better, if 485 is only divisible by 1 and 485, then it is a prime number, and if 485 is divisible by more than 485 and 1, then it is a composite number.
The factors of 485 are as follows:
1, 5, 97, 485
Therefore, since 485 is divisible by more than one and itself, the answer to the
question "Is 485 prime or composite?" is highlighted in blue below.
composite
Is 486 prime or composite?
OK. Now you know that 485 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.
