The winning Mega Millions numbers for the $640 million jackpot: 46, 23, 38, 4, 2, Mega Ball 23.
Lottery officials increased the MegaMillions lottery jackpot to $640 million, raising what was already a world-record prize.
The jackpot had stood at $540 million before Friday's announcement. The previous record jackpot was $390 million in 2007.
The odds of winning the jackpot had been set at about 1 in 176 million.
MegaMillions has drawn long lines of lottery players in stores in the 42 states plus Washington, D.C., and the Virgin Islands where tickets are sold. The world-record jackpot has also lured some residents to travel to other states to buy $1 tickets.
