The winning numbers in the Powerball lottery drawing Saturday night were 21-24-36-42-45 with Powerball 15, however there were no winners. The jackpot for the next drawing is now estimated at $400 million, which would be $230 million before taxes if taken as a lump sum. The store that sells the winning ticket also stands to walk away with a bonus of $1 million, which is the largest bonus a retailer can receive. Although $300 million is sizable jackpot, the largest prize ever was $656 million won in the Mega Millions contest on March 30, 2012. Powerball's biggest jackpot was $590.5 million, won in Florida in May by an 84-year-old widow.
