- The number is divisible by 9;
- If we remove the last digit from one number, the remaining number is divisible by 8;
- If we remove the last two digits from one number, the remaining number is divisible by 7;
- And so on until we remove the last 8 digits, in which case the remaining number is divisible by 1.
