I was trying to solve a problem but I was stuck because i am getting a compile error.

This is my error message: error: incompatible types: possible lossy conversion from long to int

div*=factorial[count];

I am confused because I am using long for both the variables, can i not multiply long with long?

This is my code:

```
/* Author- Yaswanth*/
import java.util.*;
import java.lang.*;
import java.io.*;
class Codechef
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner in=new Scanner(System.in);
int t=in.nextInt();
long factorial[]=new long[501],div=1;
factorial[0]=1;
for(int i=1;i<=500;i++){
factorial[i]=i*factorial[i-1];
factorial[i]%=1000000007;
}
while(t-->0)
{
div=1;
String st=in.next();
int n=st.length();
int characters[]=new int[n];
for(int i=0;i<n;i++){
characters[i]=(int)st.charAt(i);
}
Arrays.sort(characters);
long ans,count=1;
ans=factorial[n];
for(int i=0;i<n-1;i++){
if(characters[i]==characters[i+1]){
count++;
continue;
}
else if(characters[i]!=characters[i+1]||i==n-2)
{
div*=factorial[count];
div%=1000000007;
count=1;
}
}
System.out.println(ans/div);
}
}
}
```
