Question: Find the L.C.M. of the following expressions: x² -xy, and x³y -xy³.

Solution:
Given,

1st expression: x² -xy = x(x-y)

2nd expression: x³y -xy³
= xy (x² -y²)
= xy (x+y)(x-y)

Now,

Lowest Common Multiples (L.C.M.) = common factors * rest factors

= x (x-y) * y(x+y)
= xy (x+y)(x-y)
= xy (x² -y²)
