  • Firstly, list the few multiples of X and Y. 
  • Then, you can mark the common multiples between X and Y. 
  • Lastly, select the lowest number. That is the least common multiple of X and Y. 


Let us take an example mentioned below to understand more about LCM. 


Example 1: Find the LCM of 4 and 5. 

First few multiples of 4 = 4, 8, 12, 16, 20, 24, 28 and so on.
