Pentru a determina dacă două numere sunt prime între ele, se folosește funcția math.gcd() din Python, care calculează cel mai mare divizor comun al acestora și verifică dacă acesta este egal cu 1. La final, numărul de perechi de numere prime între ele este afișat.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
