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?

Notice that each row and each column contains the numbers 1, 1, 2, 3, 4, 5, 6, 7
$$ \begin{array}{ a b c d } 4*7 & 1*6 & 3*1 & 2*5 & \\ 3*5 & 2*1 & 4*6 & 1*7 &\\ 1*1 & 4*5 & 2*7 & 3*6 &\\ 2*6 & 3*7 & 1*5 & 4*1 &\\ \end{array} $$
