Hi Friend,

Try the following code:

public class PerfectNumber{

public static void main(String[]args){
int sum=0, x=0;
for(int num=1;num<500;num++){
for(int i=1;i<num;i++){
x=num%i;
if(x==0)
sum=sum+i;
}
if(sum==num){
System.out.println("Perfect Number is: "+num);
System.out.println("Factors are: ");
for(int i=1;i<num;i++){
x=num%i;
if(x==0)
System.out.println(i);
}
}
sum=0;
}
}
}

Thanks
