Which number can be divide by 9?
Rule A number is divisible by 9 if the sum of the digits are evenly divisible by 9. Examples of numbers that satisfy this rule and are divisible by 9. 4 + 5 + 1 + 8 = 18 which is divisible by 9, so 4,518 is divisible by 9. 6 + 9 + 9 + 3 = 27 which is divisible by 9 so, the entire number is divisible by 9.
What is divided by 9?

What is the divisibility of 9?
The Rule for 9: The prime factors of 9 are 3 and 3. So we can use a very similar rule to determine if a number is divisible by 9. Basically, we will see if the sum of the digits is divisible by 9. If it is, then the actual number is also divisible by 9. This is done the same way we checked the rule for 3.
