numpy.gcd(arr1, arr2, out = None, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None) : This mathematical function helps user to calculate GCD value of |arr1| and |arr2| elements.
Greatest Common Divisor (GCD) of two or more numbers, which are not all zero, is the largest positive number that divides each of the numbers.
Example: Finding GCD of 120 and 2250
120 = 2^3 * 3 * 5 2250 = 2 * 3^2 * 5^3 Now, GCD of 120 and 2250 = 2 * 3 * 5 = 30
Parameters :
arr1 / arr2 : [array_like]Input array.Return : Greatest Common Divisor (GCD) of two or more numbers.
Code :
# Python program illustrating # gcd() method import numpy as np arr1 = [120, 24, 42, 10] arr2 = [2250, 12, 20, 50] print ("arr1 : ", arr1) print ("arr2 : ", arr2) print ("\nGCD of arr1 and arr2 : ", np.gcd(arr1, arr2)) print ("\nGCD of arr1 and 10 : ", np.gcd(arr1, 10)) |
Output :
arr1 : [120, 24, 42, 10] arr2 : [2250, 12, 20, 50] GCD of arr1 and arr2 : [30, 12, 2, 10] GCD of arr1 and 10 : [10, 2, 2, 10]
