LOS ANGELES — An eye-popping and unprecedented Powerball jackpot whose rise to $1.6 billion became a national fascination will be split three ways.

The winners’ identities remain a mystery, but they bought their tickets in Florida, Tennessee and a Los Angeles suburb where even lottery losers were celebrating Thursday that such heady riches were won in their modest city.

The winners of the world-record jackpot overcame odds of 1 in 292.2 million to land on the numbers drawn Wednesday night, 4-8-19-27-34 and Powerball 10. They can take the winnings in annual payments spread over decades or a smaller amount in a lump sum.

The California ticket was sold at a 7-Eleven in Chino Hills, Calif., lottery spokesman Alex Traverso told The Associated Press. The winning ticket in Tennessee was sold in Munford, north of Memphis, according to a news release from lottery officials in that state.

The California store and its surrounding strip mall immediately became a popular gathering spot in the usually quiet suburb of 75,000 people. Hundreds of people, from news crews to gawkers, crowded the store and its parking lot.

“It’s history. We’re all so excited for our city,” Rita Talwar, 52, who has lived in Chino Hills for 30 years, told the local newspaper, the San Bernardino Sun.

The estimated jackpot amounts had risen steadily since Nov. 4, when it was reset at $40 million.
