# Four-by-four table with equal row and column products

Is there a way of filling a $4\times4$ table with $16$ distinct integers from $1,2,\ldots,100$ such that the products of the numbers in every row and in every column are all equal to each other?

The largest prime number that could be in the table is 23. – Tony Ruth Feb 27 at 18:35

Notice that each row and each column contains the numbers 1, 1, 2, 3, 4, 5, 6, 7

$$\begin{array}{ a b c d } 4*7 & 1*6 & 3*1 & 2*5 & \\ 3*5 & 2*1 & 4*6 & 1*7 &\\ 1*1 & 4*5 & 2*7 & 3*6 &\\ 2*6 & 3*7 & 1*5 & 4*1 &\\ \end{array}$$
