What is LCM and how do we find the LCM of given numbers?
Solution:
LCM or least common multiple of two or more numbers is the smallest positive number that is a multiple of those two or more numbers
Example:
Find the least common multiple of 4 and 10:
The multiples of 4 are: 4, 8, 12, 16, 20, ...
and the multiples of 10 are: 10, 20, ...
The least of these common multiples is 20
So LCM of 4 and 10 is 20.
Also LCM = $\frac{ Product \ of \ numbers}{HCF}$
