Python Program for Common Divisors of Two Numbers Last Updated : 23 Jul, 2025 Comments Improve Suggest changes 3 Likes Like Report Given two integer numbers, the task is to find the count of all common divisors of given numbers? Input : a = 12, b = 24Output: 6Explanation: all common divisors are 1, 2, 3, 4, 6 and 12Input : a = 3, b = 17Output: 1Explanation: all common divisors are 1Input : a = 20, b = 36Output: 3Explanation: all common divisors are 1, 2, 4 Python # Python Program to find # Common Divisors of Two Numbers a = 12 b = 24 n = 0 for i in range(1, min(a, b)+1): if a%i==b%i==0: n+=1 print(n) # Code contributed by Mohit Gupta_OMG Output6 Time Complexity: O(min(a, b)), Where a and b is the given number.Auxiliary Space: O(1) Please refer complete article on Common Divisors of Two Numbers for more details!
