Henry Ernest Dudeney/Modern Puzzles/175 - Is it Very Easy

 * Is it Very Easy?
 * Here is a simple magic square, the three columns, three rows, and two diagonals adding up to $72$.


 * $\begin{array}{|c|c|c|}

\hline 27 & 20 & 25\\ \hline 22 & 24 & 26 \\ \hline 23 & 28 & 21 \\ \hline \end{array}$


 * The puzzle is to convert it into a multiplying magic square,
 * in which the numbers in all the eight lines if multiplied together give the same product in every case.
 * You are not allowed to change, or add to, any of the figures in a cell
 * or use any arithmetical sign whatever!
 * But you may shift the two figures within a cell.
 * Thus, you may write $27$ as $72$, if you like.
 * These simple conditions make the puzzle absurdly easy, if you once hit on the idea;
 * if you miss it, it will appear to be an utter impossibility.
