To determine if 486 is a prime number or a composite number, we simply look at the factors for 486.
If the factors of 486 are only 486 and 1, then we know that 486 is a prime number. Otherwise, 486 is a composite number.
To explain better, if 486 is only divisible by 1 and 486, then it is a prime number, and if 486 is divisible by more than 486 and 1, then it is a composite number.
The factors of 486 are as follows:
1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
Therefore, since 486 is divisible by more than one and itself, the answer to the
question "Is 486 prime or composite?" is highlighted in blue below.
composite
Is 487 prime or composite?
OK. Now you know that 486 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.
