### How to use LCM Calculator

Lcm stands for the least common multiple. By the term Lcm, we mean the process of finding the number, which is the least common multiple of all the given numbers.  Let’s first see what is a multiple.  By the word multiple, we mean that the number which exactly divides the given number. Thus if we say that 12 is the multiple of 3, it means that the number 3 completely divides the number 12.
Now if we  have to find the Lcm  of the two numbers say 3 and 6, then we will first write the  multiples of 3 and the multiples of 6, which are as follows :

Multiples of 3 = 3 , 6 , 9, 12, 15, 18,  21,  24,  . . . .  . .
Similarly, we have the multiples of  6 = 6,  12,  18, 24,  . . . . . .
Now we will observe the common multiples of the two numbers 3 and 6 as 6, 12, 18, 24, 30 . . . . which means that these numbers  divides both the numbers completely.  Out of these numbers we say that the number 6 is the smallest number. So we come to the conclusion that  6 is the L.C. M of  the numbers 3 and 6.
In the same way we can find the LCM of 3 or more numbers also. We must remember that the LCM of 1 and any number n is n itself.

We can also download Lcm Calculator or use it online to understand the concepts of Lcm. To understand the concept of the Circle Graph, we can study and learn from the books of CBSE or take the help of online math tutor.  We also have CBSE Sample Paper online which the students can download and  use as a guidance tool for the  students preparing for the exams and in the next session we will discuss about
