It does work, but is not quite the answer to the problem. This is because this solution will only return the smallest integer $z$ such that z * lst is a integer list, what I need is the smallest positive real $z$.

| Mar 16, 2020 at 23:20 | comment | added | Victor Gustavo May | What if my list is not made up of rationals, but I wanted some degree precision, namely 10 digits. How could I transform my list into a list of rationals? so that I can use this | |
