There were match five winners who won $1 million in California, Indiana, Oregon and Virginia.The last billion-dollar Powerball prize -- the jaw-dropping $2.04 billion -- was won in California in November of last year. The next largest prize -- $1.586 billion – was won in Jan. 2016 in California, Florida and Tennessee.Lottery officials said that while the odds of winning the big jackpot may be astronomical, the chances of winning a smaller prize were much better at 1 in 24.9.Jackpot winners can either take the money as an immediate cash lump sum or in 30 annual payments over 29 years.
