$$\mbox{prime factorization} \\\\
\begin{array}{rccccc}
8 =& 2^{\textcolor[rgb]{1,0,0}{3}}\ *& 3^0\\
3 =& 2^0 \ *& 3^{\textcolor[rgb]{1,0,0}{1}}\\
4 = & 2^2 \ *& 3^0\\
\hline
\mbox{in each case the biggest exponent}
& 2^{\textcolor[rgb]{1,0,0}{3}}
\ *& 3^{\textcolor[rgb]{1,0,0}{1}}
&= 24 = LCM \\
\end{array}$$
