Question

What is LCM?

Answer 1

Least common multiple (LCM):

The full form of LCM is the Least Common Multiple. LCM is the least number that is exactly divisible by two or more numbers. And LCM of two numbers $a$ and $b$is denoted as$\mathrm{LCM}(a,b)$. LCM is also called the Least Common Divisor

Example: Consider two numbers $6$ and$18$.

$$\begin{gathered} \mathrm{Multiple}\mathrm{of}6=6,12,18,24,30,\dots \\ \mathrm{Multiple}\mathrm{of}18=18,36,54,72,... \end{gathered}$$

Here, $\mathrm{LCM}(6,18)=18$

Thus, LCM is the least number that is exactly divisible by two or more numbers.
