How to solve for the sides of a rectangle whose sides are natural numbers given its area is a known natural...

$begingroup$


This may not be the best way to formulate the question but I am looking for a method to solve the following equation $d cdot n'=n$ where $d, n', n in mathbb{N}$ and $n neq1$ is known. How should I approach this problem? Are there guaranteed solutions?

    You have basically asked if it is possible to find a factorization of $n$. If you forbid the trivial factorization of $1cdot n = n$, then this problem is at least as hard as determining if $n$ is prime, and probably not harder than breaking the (multiprime) RSA encryption scheme.

They would be any two factors of $n$.




  • If $n$ is prime, then the numbers are $1,n$.

  • If $n=1$, $d=n'=1$.

  • If $n$ is composite, take any two factors $d, n'$ of $n$ such that $dn' = n$.


Solutions are indeed guaranteed for all $n in mathbb{N}$.



This follows from the facts that by definition the factors of a natural number are in turn also natural numbers, and that all numbers are prime, composite, or $1$.
