I need help with this program. Please help

Question

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
int ans = 0;
int cona;
int conb;
int fg = 0;
System.out.println("Hi! I find the LCM of 2 numbers!");
System.out.println("What is the first number?");
Scanner MyVar = new Scanner(System.in);
int FN = MyVar.nextInt();
System.out.println("What is the second number?");
Scanner MyVat = new Scanner(System.in);
int SN = MyVat.nextInt();
int[] faray = new int[10001];
int[] saray = new int[10001];
for (int x = 0; x <= 10000; x++) {
cona = FN * x;
conb = SN * x;
faray[x] = cona;
saray[x] = conb;
}
for (int a:faray) {
if (fg == 0) {
for (int b:saray) {
if (a == b) {
ans = a;
fg++;
break;
}
}
}
}
System.out.println("The LCM of " + FN + " and " + SN + " is " + ans);
}
}

Answer 1

Please send the link of your code instead...
So that we can test it

Answer 2

avoid to compare 0==0 at begin of arrays eg

for (int b:saray) {
if (a == b && a!=0) {

for Sololearn do not use two Scanner(System.in)
