The ticket bought in Rancho Cucamonga matched five of the numbers, but missed the Mega number.
The 5/5 ticket is worth about $619,804, according to the California Lottery.
Having that one extra number would have jumped that payoff to $720 million.
The numbers in Friday's draw are 29, 40, 47, 50, 57 and the Mega number is 25.
The drawing was the 27th since the last time a ticket with all six numbers was sold. The jackpot for the next drawing Tuesday is estimated at $820 million.
The odds of matching all five numbers and the Mega number is 1 in 302,575,350, according to the California Lottery. The overall chance of winning a prize is 1 in 24.
Meanwhile, the Powerball jackpot was approaching near-record levels before a store in downtown Los Angeles sold the winning ticket for Wednesday's drawing, worth an estimated $1.08 billion.
