<reasoning>

Find the LCM of the numerical coefficients

\[

$$\begin{aligned} &\text{lcm}(12, 20) = 60 \end{aligned}$$

\]

Find the highest power of each variable

\[

$$\begin{aligned} &u: \max(5, 4) = 5 \\ &x: \max(6, 7) = 7 \\ &v: \max(8, 0) = 8 \end{aligned}$$

\]

Combine the numerical LCM and variable powers

\[
\text{LCM} = 60u^5x^7v^8
\]
