There are infinitely many multiples of 3. One interesting fact about multiples of 3 is that the sum of the digits of each multiple is always equal to either 3, 6, or 9. All alternative multiples of 3, starting from 6 and including 12, 18, 24 and so on, are also multiples of 6. Some multiples of 3 are also multiples of 9, and the sum of the digits of each of these multiples is always equal to 9.
