Question

For the given monomials $x^{3}yz,z^{4}y{x}^3,x{y}^4{z}^5$ find the L.C.M.

• A. $x^2{y}^4{z}^5$
• B. $x^3{y}^4{z}^5$
• C. $x^3{y}^6{z}^5$
• D. $x^6{y}^6{z}^{1}0$

Answer 1

The correct option is B $x^3{y}^4{z}^5$

Highest exponent of $x$ among three terms is $3$

highest exponent of $y$ among three terms is $4$

And the highest exponent of $z$ among three terms is $5$

Hence LCM is $x^3{y}^4{z}^5$
