Answer 1

Flag is always false...I do litle changes to your code, check it here:https://code.sololearn.com/cf0Jx2cbE4f3/?ref=app

Answer 2

I got the same as Cristian Baeza Jimenez by changing the print line to be
if (i==num) System.out.println(num);

I didn't mess about with your unused flag.

Answer 3

Sure mate, I literally only changed that line..

Edit: hold up, it doesn't work correctly!!! sorry.

EDIT2: fixed it, used the flag, moved the assignment of num, only check factors to half of i.

Do you see what I changed, and why??
