1, 9, and 81 are the only multiples of 81
81, 162, 243, 324
Techcially all numbers are divisible by 81, however many would result in a decimal answer. If you mean how many numbers are divisible by 81 and have an integer answer, then it is "all multiples of 81" - e.g 81 x 2, 81 x 3 etc...81, 162, 243 and keep adding 81 forever.
They are all multiples of 9. Their common multiples are 405, 810, 1215 and so on.
Oh, what a happy little question! Multiples of 27 include 27, 54, 81, and so on. Multiples of 9 include 9, 18, 27, and more. Multiples of 15 are 15, 30, 45, and beyond. And multiples of 81 include 81, 162, 243, and many more. Just remember, each number has its own special multiples waiting to be discovered!
