One of them said he was at work ''on smoko'' when a colleague mentioned a winning ticket had been sold in Mosgiel.
''I thought 'That's some lucky bugger','' the winner said.
''Then I picked up a copy of the paper and checked our ticket, and they were our numbers. I just started shaking, but I didn't have a heart attack,'' he said.
The friends said they were still trying to comprehend the cash prize.
''We don't usually have much luck with our tickets, so to win so much is dumbfounding,'' they said.
One of the winners said it was a good feeling to see the money in his bank account.
''I've been so nervous the past week thinking about all the possibilities that the money will bring. It's a lot to take in,'' he said.
