Question

Find LCM of the following expressions :
$4a^2{b}^{2}c$ and $6a{b}^{2}d$

Answer 1

$4a^2{b}^{2}c=2\times 2\times a\times a\times b\times b\times c$

$6a{b}^{2}d=2\times 3\times a\times b\times b\times d$

$\therefore$L.C.M$=2\times 2\times 3\times a\times a\times b\times b\times c\times d$

$=12a^2{b}^{2}cd$
