Properties of Multiples of 9

Here are a few properties of multiples of 9:

• The smallest multiple of 9 is the number 9.
• Every number that is a multiple of 9 is greater than or equal to the number 9.
• If you calculate the difference between the numbers which have the same set of digits, the difference will be a multiple of 9. For example, take the numbers 217 and 127. The difference between them is 90, 217-127=90. 90 is the 10th multiple of 9. Another example is 865-568=297. 297 is the 33rd multiple of 9.
• Since there are an unlimited number of possible multiples of a number, the number 9 has an infinite number of multiples.
