What is Least Common Multiple
Least Common Multiple or LCM of two numbers a nd b is the smallest postive integer which is evenly divisible by the numbers a and b. It is called lowest common multiple or Lowest common divisible.
LCM can be obtained using prime fractorization technique. Here we find the LCM using the below Formula
LCM (a,b) = \frac { HCF(a,b)}{a \times b}
How the LCM calculator works
First we need to input the two positive integers whose LCM is required to be calculated
Now HCF of a and b is calculated using Euclid Division Lemma
Now the LCM is obtained using the formula
LCM (a,b) = \frac { HCF(a,b)}{a \times b}
LCM of more than two Numbers
Note
Enter the values of the more than 2 numbers seperated by commas whose gcf need to be calculated Example 2,3,4

Formula used
$ LCM(a,b,c,d) = LCM(LCM(LCM(a,b),c),d)$

Example of Few questions where you can use this formula
Find the LCM of 12,8,16,32
Find the LCM of 3,8,18,36
How the LCM calculator works
First we need to input the positive integers whose LCM is required to be calculated
Now first we calculate the LCM of first two values using the formula
LCM (a,b) = \frac { HCF(a,b)}{a \times b}
Now the LCM obtained and third number is taken and LCM is again obtained using the same technique.
We keep doing until all numbers are absorbed, final LCM is obtained
