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
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.
Not all of them are. Consider 27. 6 and 9 share a lot of common multiples because they share a common factor.
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.
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.
the common multiples between 1 and 100 for 9 and 10 are just 90!
The common multiples of 9 and 21 are 63, 126, 189 and so on.
Multiples of 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.
The lowest common multiple of 7 and 9 is 63. The common multiples of 7 and 9 are therefore the infinite set of multiples of 63. Thus, the common multiples of 7 and 9 are 63, 126, 189, 252, 315, 378, 441, 504, 567, 630, 693, and so on.
All multiples of 90.
You can't have common multiples if they have nothing to be in common with however the first 3 multiples of 9 are 9,18 and 27 Think of just your times tables when finding out Multiples to find the first 5 multiples just count by 9's until you have said 5 numbers and Bingo
The common multiples of 4 and 9 are 36, 72, 108 and so on.

Common Multiples are multiples which are common to both numbers So Multiples of 9 are 9, 18, 27, 36 etc... Multiples of 27 are 27, 54, 81 etc... you can work out the least common multiple as 27 We can see that 9 is a factor of 27 so all multiples of 27 are a common multiple with 9. But as there is no upper limit we can not work out a greatest common multiple as they bigger they get the closer they get to infinity! You tend to work out Greatest Common Factor and Least Common Multiple with regards numbers.
90 is the least common multiple of 9 and 10
