LCM Stands for Least Common Multiple or Lowest Common Multiple.
To get the LCM, list down the multiples of each number until you get the smallest number that can divide the two or more given numbers.
Example 1
the LCM of 4 and 6 is
4 : 4,8,12,16,20,24,28,32,36.....
6: 6, 12,18,24,30,36......
LCM of 4 and 6 is 12 because it is the lowest number that can divide the two.
Look at another example to get LCM.
