Solution
The correct option is A12x3y3z We know that the least common multiple (LCM) is the smallest number or expression that is a common multiple of two or more numbers or algebraic terms.
We first factorize the given monomials 3x2yz and 4x3y3 as shown below:
3x2yz=3×x×x×y×z4x3y3=2×2×x×x×x×y×y×y
Now multiply all the factors, using each common factor only once, therefore, the LCM is:
