In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math.gcd() function compute the greatest common divisor of 2 numbers mentioned in its arguments.
Syntax: math.gcd(x, y) Parameter: x : Non-negative integer whose gcd has to be computed. y : Non-negative integer whose gcd has to be computed. Returns: An absolute/positive integer value after calculating the GCD of given parameters x and y. Exceptions : When Both x and y are 0, function returns 0, If any number is a character, Type error is raised.
Time Complexity: O(1)
Auxiliary Space: O(1)
Code #1:
Python3
import math
print ("The gcd of 60 and 48 is : ", end ="")
print (math.gcd(60, 48))
|
Output:
The gcd of 60 and 48 is : 12
Code #2:
Python3
import math
print ("math.gcd(44, 12) : ", math.gcd(44, 12))
print ("math.gcd(69, 23) : ", math.gcd(65, 45))
|
Output:
math.gcd(44, 12) : 4
math.gcd(69, 23) : 5
Code #3: Explaining Exception.
Python3
import math
print ("The gcd of 0 and 0 is : ", end ="")
print (math.gcd(0, 0))
print ("\nThe gcd of a and 13 is : ", end ="")
print (math.gcd('a', 13))
|
Output:
The gcd of 0 and 0 is : 0
The gcd of a and 13 is :
