Smallest Multiple of M

The program must accept two integers M and N as the input. Then the program must print the smallest multiple of M which is also divisible by M+N as the output.

Boundary Condition(s):
1 <= M, N <= 10^5

Input Format:
The first line contains the values of M and N separated by a space.

Output Format:
The first line contains the smallest multiple of M which is also divisible by M+N.

Example Input/Output 1:
Input:
6 14

Output:
60

Explanation:
The sum of 6 and 14 is 20.
The smallest multiple of 6 which is divisible by 20 is 60.
Hence the output is 60

Example Input/Output 2:
Input:
12 5

Output:
204

program in C:

#include<stdio.h>

int main()

{int a,b;

scanf("%d %d",&a,&b);

int c=a+b,d=a;

for(int i=1;i>=1;i++)

{d=a*i;

if(d%c==0)

{ printf("%d",d); 

break;} 

}

}
