Powerball Product Group Chair Charlie McIntyre says the $758.7 million jackpot claimed by a ticket sold in Massachusetts is the largest grand prize won by a single lottery ticket in U.S. history. In a statement early Thursday, McIntyre also says six other tickets won $2 million apiece, and 34 others are worth $1 million. The lucky numbers for the second largest lottery prize in U.S. history were 6, 7, 16, 23 and 26, and the Powerball number was 4.
