# Python program to demonstrate Basic Euclidean Algorithm
# Function to return gcd of a and b
def gcd(a, b):
if a == 0 :
return b
return gcd(b%a, a)
a = 10
b = 15
print("gcd(", a , "," , b, ") = ", gcd(a, b))
a = 35
b = 10
print("gcd(", a , "," , b, ") = ", gcd(a, b))
a = 31
b = 2
print("gcd(", a , "," , b, ") = ", gcd(a, b))

Output:
GCD(10, 15) = 5 GCD(35, 10) = 5 GCD(31, 2) = 1
Time Complexity: O(Log min(a, b))
Auxiliary Space: O(Log min(a, b)), due to recursion stack.
