The winning numbers drawn Friday night for the record $640 million Mega Millions jackpot were:
2-4-23-38-46 23 (Megaball)
The jackpot, if taken as a $462 million lump sum and after federal tax withholding, works out to about $347 million. With the jackpot odds at 1 in 176 million, it would cost $176 million to buy up every combination. Under that scenario, the strategy would win $171 million - less if your state also withholds taxes.
