Is there a way of filling a 4×4 table with 16 distinct integers from 1, 2, ..., 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
$$ \begin{array}{ a b c d } 4*7 & 1*6 & 3*1 & 2*5 & \\ 3*5 & 2*1 & 4*6 & 1*7 &\\ 1*1 & 4*5 & 2*7 & 3*6 &\\ 2*6 & 3*7 & 1*5 & 4*1 &\\ \end{array} $$
