     int big=Integer.parseInt(br.readLine());
     int small=Integer.parseInt(br.readLine());
     int rem=1;//Intialize Remainder =1
     while(rem!=0)//while remainder is not equal to 0
      {
        rem=big%small; //FInd the remainder
        if(rem!=0)//If the remainder is not equal to 0,proceed
         {

            small=rem;
          }
      }
      // Print the LCM
    System.out.println(small);
