To determine if 495 is a prime number or a composite number, we simply look at the factors for 495.
If the factors of 495 are only 495 and 1, then we know that 495 is a prime number. Otherwise, 495 is a composite number.
To explain better, if 495 is only divisible by 1 and 495, then it is a prime number, and if 495 is divisible by more than 495 and 1, then it is a composite number.
The factors of 495 are as follows:
1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
Therefore, since 495 is divisible by more than one and itself, the answer to the
question "Is 495 prime or composite?" is highlighted in blue below.
composite
Is 496 prime or composite?
OK. Now you know that 495 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.
