Beschreibung

Die Funktion gcd berechnet den größten gemeinsamen Teiler zweier ganzer Zahlen. Die Funktion erwartet zwei Zahlen und gibt eine Zahl zurück.

Syntax

gcd(Ganzzahl zahl1, Ganzzahl zahl2)

Parameter

  • zahl1 - erste Zahl aus der Menge der ganzen Zahlen
  • zahl2 - zweite Zahl aus der Menge der ganzen Zahlen

Return Value

  • Gibt eine Ganzzahl zurück

Beispiele

Standardfälle

gcd('5','20')   --> returns 5

gcd('-5','0')   --> returns 5
