In that case I guess I would just order 3 new chainrings with the same number of teeth, keep the cranks and bottom bracket, just make sure to order the right number of bolts and BCD. Simple. There's a special tool to help hold the chainring bolt in place while you unscrew it but you can make do with a flathead screwdriver or an old spoke
Edit: and the front derailleur should also be fine unless it's damaged
