How to find the LCM of numerical digits (numbers)

let us see how to find the LCM of any two or three numbers. We will show you the easiest way here in two steps :

Example : Find the  LCM of  3,6 and 9

Step 1 : write the multiplication table of 3,6,9.
              3=3*6*9*12*15*18*21*24*.......
              6=6*12*18*24*30*36*......
              9=9*18*27*36*45*54*......

Step 2: do you find any common number in all three tables above. Yes there are, but we have to choose that one whose value is least and is common in all three tables. The least valued common number above is 18.

The 18 is the Least Common Factor LCM of 3,6 and 9
