The decimal place "moves" one space to the left.
For each step, you increase the value by a multiple of 10.
The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90
Any integer that is a multiple of 10 (those are the ones that end with 0) will yield an integer if you divide it by 10. Anything else will not.
It becomes a tenth as large.
The least common multiple of 9 and 10 is 90 because it is the lowest number that both 9 and 10 divide into evenly.

40, 80, 120 and so on are multiples of both 8 and 10.
it moves left 1 digit

You divide by 10.You divide by 10.You divide by 10.You divide by 10.
The smaller multiples of 10 are: 10, 20, 30, 40, and 50.None of them is a multiple of 12.The smaller multiples of 12 are: 12, 24, 36, and 48.None of them is a multiple of 10.The smallest number that's a multiple of 10 and a multiple of 12 is . . . 60 .

Just try to divide it. If you get a whole number (when you divide on your calculator), it is a multiple; otherwise it is not.
