The holders of two winning tickets sold in Idaho and Washington will be sharing Mega Million's $355 million jackpot from Tuesday night's drawing, lottery officials said Wednesday.

The two winners will each get $177.5 million.

The winning numbers were 4, 8, 15, 25 and 47, with 42 being the Mega Ball number.

There were four Match 5 winners in Ohio, two in Kentucky and one in Indiana. They get $250,000 a piece for matching the first five numbers but not the Mega Ball.

The jackpot grew to the fourth-largest in U.S. history and the second-largest in Mega Millions history, said Arizona Lottery spokeswoman Cindy Esquer. The lottery's prize of $390 million in March 2007 remains the nation's richest on record.

UPDATE: We've learned the winning ticket was sold in Post Falls. Road trip?
