There are infinity of them
Here are some common multiples of 9:
18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126
Common multiples of 9 and 10 are all of the multiples of 90.
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
Each common multiple of 9 and 10 occurs exactly once (in the list of common multiples), so there is no common multiple that occurs the most. All common multiples of 9 and 10 are the multiples of their least common multiple which is 90.
Multiples of 9 include 9, 18, 27 and so on. For them to be common, they need to be compared to another set of multiples.Itself and any other multiples of 9
The common multiples of 9 and 21 are 63, 126, 189 and so on.
The common multiples of 9 and 11 are 99, 198, 297 and so on.
The least common multiples of the number 6 and 9 is 3.
Multiples of 90.
Not all of them are. Consider 27. 6 and 9 share a lot of common multiples because they share a common factor.
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
