63 has factors other than 1 and itself, so it is not a prime number. For example, 63 is divisible by 3. (You can check this by adding the digits of the number: 6 + 3 = 9. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 63 is a composite number.
63 = 3 x 3 x 7, so it is composite
You 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.
