They are: 72, 81 and 99 which makes three of them

30
To find the LCM of 10,40, and 100, lets list the first several multiples of these numbers:Multiples of 10: 10,20,30,40,50,60,70,80,90,100Multiples of 40: 40,80,120,160,200,240,280,320,360,400Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000We see that there is the multiple 200 shared between 40 and 100. We know that 200 is a multiple of 10, too, because 10 x 20= 200, so the lowest common multiple of 10, 40, and 100 is 200.
90
The Least Common Multiple (LCM) for 8 10 15 is 120.
the common multiples between 1 and 100 for 9 and 10 are just 90!
90 is the least common multiple of 9 and 10
The two smallest multiples of 10 are 10 and 20. For them to be common, they would need to be compared to another set of multiples.

It is: 30
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.
