Python: Find common divisors between two numbers in a given pair
Python Basic - 1: Exercise-29 with Solution
Write a Python program to find common divisors between two numbers in a given pair.
Pictorial Presentation:

Sample Solution:
Python Code:
def ngcd(x, y):
i=1
while(i<=x and i<=y):
if(x%i==0 and y%i == 0):
gcd=i;
i+=1
return gcd;
def num_comm_div(x, y):
n = ngcd(x, y)
result = 0
z = int(n**0.5)
i = 1
while( i <= z ):
if(n % i == 0):
result += 2
if(i == n/i):
result-=1
i+=1
return result
print("Number of common divisors: ",num_comm_div(2, 4))
print("Number of common divisors: ",num_comm_div(2, 8))
print("Number of common divisors: ",num_comm_div(12, 24))
Sample Output:
Number of common divisors: 2 Number of common divisors: 2 Number of common divisors: 6

What is the difference between Python's list methods append and extend?
append: Appends object at the end.
x = [1, 2, 3] x.append([4, 5]) print (x)
Output:
[1, 2, 3, [4, 5]]
extend: Extends list by appending elements from the iterable.
x = [1, 2, 3] x.extend([4, 5]) print (x)
Output:
[1, 2, 3, 4, 5]
