The Mega Millions world record stood until January 2016, when Powerball took over the crown as the lottery champion of the world with a $1.568 billion jackpot. Changes to the Mega Millions game format have made it more difficult to win the Mega Millions jackpot and as a result, Mega Millions could soon award a record-breaking jackpot and regain its title as the biggest lottery in the world.
The probability and odds can be taken into a mathematical perspective: The probability of winning the jackpot (through October 27, 2017) was 1:(75C5) x (15); that is: 75 ways for the first white ball times 74 ways for the second times 73 for the third times 72 for the fourth times 71 for the last white ball divided by 5 x 4 x 3 x 2 x 1, or 5!, and this number is then multiplied by 15 (15 possible numbers for the "Megaball"). Therefore, (75 x 74 x 73 x 72 x 71)/ (5 x 4 x 3 x 2 x 1) x 15 = 258,890,850, which means any combination of five white balls plus the Megaball has a 1:258,890,850 chance of winning the jackpot. Similarly, the odds for second prize are 1:(75C5) x (15/14) = 1: 18,492,204 chance of winning. The overall probability of winning any prize was 1 in 14.7. If there are no jackpot winners for a specific drawing, the jackpot will keep increasing, however, the odds will still remain the same.
Other winners in excess of $250 million: On December 25, 2002, Jack Whittaker, president of a construction firm in Putnam County, West Virginia, won $314.9 million ($428 million today), then a new record for a single ticket in an American lottery. Whittaker chose the cash option of $170 million, receiving approximately $83 million after West Virginia and Federal withholdings.[35]

The US Powerball is a standard lottery draw game based and operated from the golden State of California. The US Powerball has been making millionaires and multi-millionaires since its first drawing way back in 1992. With over 25 years of experience in the lottery industry, the Powerball, along with many other State lotteries, has broken through the final glass ceiling and transformed itself from an interstate lottery into a truly international lottery of global reach.
