a³ -b³, and a² +ab +b² | Find the LCM | SciPiPupil

Question: Find the L.C.M. of the following expressions: a³ -b³, and a² +ab +b².

Solution:

Given,

1st expression: a³ -b³

= (a-b)(a² +ab +b²)

2nd expression: a² +ab +b²

Now,

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

= (a² +ab +b²) * (a-b)

= (a³ -b³)
