13636131 has factors other than 1 and itself, so it is not a prime number. It is divisible by 3. (You can check this by adding the digits of the number: 1 + 3 + 6 + 3 + 6 + 1 + 3 + 1 = 24. If the sum of the digits is divisible by 3, the number itself is also divisible by 3.) Therefore, it is a composite number.

composite. 57 divided by 3 is 19. (Any number in which all the digits add up to equal a number divisible by 3 is divisible by 3. 5+7=12 which is divisible by 3.) And since 57 is divisible by more numbers than just 1 and itself it is a composite number.57 is a composite number since it can be divided by 3.57/3 = 19Composite.

63 = 3 x 3 x 7, so it is compositeYou can easily check for divisibility by 3 and 9 by adding the digits of the number. If the sum of the digits (6 + 3 = 9) is divisible by 3, then the number itself is divisible by 3. If the sum of the digits is divisible by 9, then the number itself is divisible by 9.63 is a composite number because it has more than two factors

If you add the digits together, you get 12. Since 12 is divisible by 3, 327 is also divisible by 3.
