Prime Numbers for Use in Lotteries (Lottery Trivia Answer 2010-10)

Last Week's Trivia Question #2010-10 was: 
Prime Numbers are a small subset of numbers that all lotteries contain. Helping to educate our lottery players about various strategies, we presented the following questions last week:
  • What are Prime Numbers?
  • How can they be used for playing the lottery?
A simple internet search yields the answers to these questions.
  • Prime numbers are those numbers which are divisible only by themselves and 1. The common set that lottery players will recognize are: 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, and 59. Note that the number one (1) is not a true prime number, we include it in this subset for lottery purposes only.
  • Since the use of this subset limits the number of choices a lottery player can make, the number of possible combinations is also minimized. For Powerball, all 18 numbers are playable. In Mega Millions, only 17 are valid; and in 649 games, only 16 are permitted.
  • Additionally all but the number two (2) are odd numbers. Thus players choosing this subset will be playing mostly all odd number or odd plus 1 even number.
In our opinion, these numbers are important because players can systematically reduce their playing number field with confidence in knowing that the numbers have more than random significance.
