The winning Illinois ticket was sold in the small town of Red Bud, near St Louis, and the winner used a quick pick to select the numbers, Illinois Lottery spokesman Mike Lang said.
A winning ticket also was purchased in north-east Kansas, according to the Kansas Lottery website.
Each winning ticket was expected to be worth more than 213 million dollars (£133 million) before taxes, Mr Lang said. The winning numbers in Friday night's draw were 02, 04, 23, 38 and 46, and the Mega Ball 23.
Maryland Lottery spokeswoman Carole Everett said the last time a ticket from the state won a major national jackpot was in 2008.
"We're thrilled," she said.
Americans spent nearly 1.5 billion dollars (£937 million) for a chance to hit the jackpot. The odds of winning the jackpot were 1 in 176 million.
From coast to coast, people stood in line at retail stores on Friday for one last chance at striking it rich.
