What Are Some Multiples of 9?

The list of the multiples of 9 can go on infinitely. The first 10 on the list are 9, 18, 27, 36, 45, 54, 63, 72, 81 and 90. These numbers are all divisible by 9.

A number is a multiple of 9 if it is a product of 9 and any other number; thus, if 9 is multiplied by numbers from 1 to 10, the results are: 9 x 1 = 9, 9 x 2 = 18, 9 x 3 = 27, 9 x 4 = 36, 9 x 5 = 45, 9 x 6 = 54, 9 x 7 = 63, 9 x 8 = 72, 9 x 9 = 81 and 9 x 10 = 90. The numbers 207, 486 and 657 are also multiples of 9, because 9 x 23 = 207, 9 x 54 = 486 and 9 x 73 = 657.

A number is a multiple of 9 if it is divisible by 9 and the result of that division is a whole number. To determine if a number is divisible by 9, just get the sum of its digits and check if the answer is divisible by 9. For example, the number 451 is not a multiple of 9, because 4 + 5 + 1 = 10, and 10 is not divisible by 9.
