Suppose we have two values a and b. We have to find x and y, such that ax – by = 0. So if a = 25 and b = 35, then x = 7 and y = 5.

To solve this, we have to calculate the LCM of a and b. LCM of a and b will be the smallest value that can make both sides equal. The LCM can be found using GCD of numbers using this formula −

*LCM (a,b)=(a*b)/GCD(a,b)*

#include<iostream> #include<algorithm> using namespace std; void getSmallestXY(int a, int b) { int lcm = (a * b) / __gcd(a, b); cout << "x = " << lcm / a << "\ny = " << lcm / b; } int main() { int a = 12, b = 26; getSmallestXY(a, b); }

x = 13 y = 6
