There are 10 multiples of 10 between 1 and 100: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
Multiples of 18: {18, 36, 54, 72, 90...}Multiples of 30: {30, 60, 90, 120, 150...}Therefore the LCM is 90.
15 30 45 60 75 90
Multiples of 9 are 9 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180... Multiples of 30 are 30, 60, 90, 120, 150, 180... Common multiples of 9 and 30 are 90, 180... The Least Common Multiple of 9 and 30 is 90.
30, 60, 90, 120, 150, 180
There are 10 multiples of 10 between 1 and 100: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
The multiples of 8 between 30 and 90 are: 32, 40, 48, 56, 64, 72, 80, and 88.
30, 60, 90 and so on. Multiples of 30.
Multiples of 18: {18, 36, 54, 72, 90...}Multiples of 30: {30, 60, 90, 120, 150...}Therefore the LCM is 90.
They are any multiples of 30
3 of them.

24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96
There are 6 multiples of 15 in 100. They are: 15, 30, 45, 60, 75, and 90
Many 'fractions' can be easily created using ratios of multiples of 30: Multiples:30 60 90 120 150 . . . Ratios:30/1, 60/2, 90/3, 120/4, 150/5 . . .
There are infinite common multiples for a set of numbers. So it is not possible to write down all the common multiples. Some common multiples of 15, 30 and 45 are 90, 180, 270, 360,... There is another way to find common multiples: Write the multiples of LCM(15, 30, 45). Actually the common multiples of a set of numbers are the multiples of their LCM. LCM of 15, 30 and 45 is 90. And the multiples of 90 are 90, 180, 270, 360, 450, 540,... which are the common multiples of 15, 30 and 45.
30, 60, 90 and so on are multiples of 30.
