If a matrix has 12 elements, what are the possible orders it can have? What, if it has 7 elements?

Explanation

We know , if a matrix is of order `mxxn`, it has mn elements, we will find all ordered pairs of natural numbers, whose porduct is 12.
Thus, all possible ordered pairs are `(1,12),(12,1),(2,6),(6,2),(3,4)(4,3)`.
Hence, possible orders are `1xx12,12xx1,2xx6,6xx2,3xx4 and 4xx3`.
If the matrix has 7 elements, then possible orders will be `1xx7 and 7xx1` .
