Math Trivia :)

The 772-778 digits of pi are 9999998, the greatest sum of 7 consecutive digits in the first 1,000,000 or so digits.

If you need to remember pi, just count the letters in each word in the sentence: "May I have a large container of coffee?" If you get the coffee and are polite and say "Thank you," you get two more decimal places. [3.141592653...]

There are 2,598,960 five-card hands possible in a 52-card deck of cards.

The largest prime number is 13,395 digits long; more than the number of atoms in the universe.

2 and 5 are the only primes that end in 2 or 5.

1 and 2 are the only numbers where they are the values of the numbers of factors they have.

142857 is a cyclic number, the numbers of which always appear in the same order but rotated around when multiplied by any number from 1 to 6. 142857 * 2 = 285714 142857 * 3 = 428571 142857 * 4 = 571428 142857 * 5 = 714285 142857 * 6 = 857142

111,111,111 x 111,111,111 = 12,345,678,987,654,321
