    What is that 6 doing there in the first denominator? Was that a typo?

    Lemme break down the first denominator a sec, maybe we can see what's going on.\[\Large\rm 50x^4y^3=25\cdot2 x^1 x^3y^1y^2=\color{orangered}{25xy^2}\cdot2x^3y\]

    So I broke down the first denominator so that it contains the second denoinator (orange) and a little bit more.

    To get your LCM, you would multiply the second fraction by 2x^3y. That would finish things up for you. So it looks like the LCM is just going to be that whole bottom left side since it contains the right denominator, and more.
