    According to the divisibility rule for 9, we need to add the digits of 123 together: 1 + 2 + 3 = 6. Since 6 is not divisible by 9, the number 123 is not divisible by 9.

    How it Works: Beginners Welcome

    Q: Can any number be divided by 9 using this rule?

    The divisibility rule for 9 states that a number can be evenly divided by 9 if the sum of its digits is also divisible by 9. This rule can be applied to numbers of any length. For instance, if we take the number 18, the sum of its digits is 1 + 8 = 9, which means 18 is divisible by 9. Another example is the number 27; the sum of its digits is 2 + 7 = 9, indicating that 27 is also divisible by 9.
