I assume the answer is 6:

\(\begin{array}{|r|r|r|r|} \hline \text{product} & 2 & 4 & 7 & 9 \\ \hline 2 & 4 & 8 & \color{red}14 & \color{red}18 \\ \hline 4 & 8 & 16 & \color{red}28 & 36 \\ \hline 7 & \color{red}14 & \color{red}28 & 49 & 63 \\ \hline 9 & \color{red}18 & 36 & 63 & 81 \\ \hline \end{array}\)
