For this problem we should find the common greatest factor of 80 and 64, by decomposing them in their prime factors. We have the following:


\begin{gathered} \text{Prime factorizations:} \\ 80=2\cdot2\cdot2\cdot2\cdot5 \\ 64=2\cdot2\cdot2\cdot2\cdot2\cdot2 \end{gathered}

Since 2 is repeated 4 times, we have that the greatest common factor is: 2x2x2x2=4x4=16. Therefore, Mr. Panilio can make 16 containers.
