BALTIMORE >> The record-breaking Mega Millions jackpot climbed to $656 million on Monday, though no one holding one of the three winning tickets has come forward yet to claim a share of the prize, officials said.

Three tickets — one each in Kansas, Illinois and Maryland — will split the jackpot, which officials said Monday was higher than previously estimated. It is now at $656 million, after sales from the 44 state lotteries were totaled, up from the previously reported $640 million. That means each winner would receive roughly $218 million apiece before taxes.

Winners in all three states have several months — in the case of Kansas, a year — to claim the prize. Both Maryland and Kansas allow winners to remain anonymous, though the winner in Illinois will be identified. The three tickets matched all six numbers: 2-4-23-38-46 and the Mega Ball, 23.

In Maryland, the New York Post reported Monday that a McDonald’s employee claimed to hold the winning ticket and planned to contact lottery officials Monday. But lottery spokeswoman Carole Everett said no one had come forward with the ticket sold at a 7-Eleven store in Milford Mill outside Baltimore.

The winning ticket in Illinois was sold at a convenience store in the small town of Red Bud, south of St. Louis. Kansas officials had not yet revealed the store where that state’s winning ticket was purchased.
