The factors of $72$ are $1,2,3,4,6,8,9,12,18,24,36,72$. The factors can be organized as such:
- $m=1,2,3,4,6,8$, and
- $n=72,36,24,18,12,9$.
Knowing the symmetric properties and that the $12$ factors exist. Is there a way to rewrite $n$ as a function of $m$ without actually diving $72$ by $m$? I tried adding and subtracting $m$ and $n$ to find a pattern as to get a clue as to what value the other might be without actually dividing.
