Como encontrar divisores comuns de dois números no CPP
// C++ implementation of program
#include <bits/stdc++.h>
using namespace std;
// Function to calculate gcd of two numbers
int gcd(int a, int b)
{
if (a == 0)
return b;
return gcd(b % a, a);
}
// Function to calculate all common divisors
// of two given numbers
// a, b --> input integer numbers
int commDiv(int a, int b)
{
// find gcd of a, b
int n = gcd(a, b);
// Count divisors of n.
int result = 0;
for (int i = 1; i <= sqrt(n); i++) {
// if 'i' is factor of n
if (n % i == 0) {
// check if divisors are equal
if (n / i == i)
result += 1;
else
result += 2;
}
}
return result;
}
// Driver program to run the case
int main()
{
int a = 12, b = 24;
cout << commDiv(a, b);
return 0;
}
