Question

Find the Least Common Multiple (LCM) by listing the multiples.

$\text{11 and 12}$

Answer 1

Finding the Least Common Multiple

$$\begin{gathered} \text{Multiples of 11 are 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132....} \\ \text{Multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144.....} \\ \text{Common multiples of 11 and 12 are 132,.. ......} \\ \text{The lowest common multiple of 11 and 12 = 132} \end{gathered}$$

Hence L.C.M. of $\text{11 and 12 is 132}$.
