Jon's MENSA Question of the Day

--posted by JRJ on 4/07/2006

You are decorating for spring, and you've found a bargain: a huge box of beautiful decorated tiles, enough to provide a border in two rooms. You really can't figure out how to arrange them, however. If you set a border of two tiles all around, there's one left over; if you set three tiles all around, or four, or five, or six, there's still one tile left over. Finally, you try a block of seven tiles for each corner, and you come out even. What is the smallest number of tiles you could have to get this result?
