At least two people have matched the winning numbers in Tuesday night's $636 million Mega Millions jackpot.

One winning ticket was sold in Georgia, and the other was sold in California, lottery officials said.

The winning numbers were 8, 14, 17, 20 and 39, with a Megaball of 7.

Strong sales boosted the jackpot to $636 million from the previous estimate of $586 million, lottery officials announced late Tuesday morning.

This jackpot was so large in part because Mega Millions, in a sense, became tougher to win. The prize rises with each miss, and no one has won it since organizers increased the pool of numbers to choose from -- making astronomical odds even longer -- back in October.
