Python gcd for list

Question

I want to calculate gcd for a list of numbers. But I don't know what's wrong with my code.

A = [12, 24, 27, 30, 36]   def Greatest_Common_Divisor(A):     for c in A:         while int(c) > 0:             if int(c) > 12:                 c = int(c) % 12             else:                 return 12 % int(c)     print Greatest_Common_Divisor(A) 

Answer 1

here is the piece of code, that I used:

from fractions import gcd from functools import reduce def find_gcd(list):     x = reduce(gcd, list)     return x 

Answer 2

As of python 3.9, python got built-in support for calculating gcd over a list of numbers.

import math A = [12, 24, 27, 30, 36] print(math.gcd(*A)) 

Output:
