30 UV led circuit (self.askelectronics)

Hello! I bought 30 simple UV leds (those with a big and a small leg, not a single strip). I'm trying to build a UV station to dry my resin but idk how to proceed. I tryed watching some videos but there is a lot of math to build that and I can't do it. I have 30 led lights, 5 resistors of 100 and 5 of 300. I wanted to use AA batteries. Do I need 8 of them?? Its not going to be turned on for long, just some 30 seconds at a time.

Can someone help me?

Three in series per 300 ohm resistor would be OK with those.
