Your number is up…

From the admirable Tonya Khovanova, everything one could want to know about a number– any number:  Number Gossip.

Consider the results returned for your correspondent’s favorite pair of digits, 27:

– 27 is the only number which is thrice the sum of its digits
– 27 is the first composite number not divisible by any of its digits
– 27 is the largest number that is the sum of the digits of its cube
– 27 is the only 2-digit number in which the sum of digits is equal to the sum of prime factors (27 = 3 * 3 * 3 and 2 + 7 = 3 + 3 + 3 = 9)
– A 10,000-day-old person is 27 years old
– 27 is the smallest cube out of two known with only prime digits (the other cube is 3375)
– A web page about 27: <http://27.chrismore.com/>The Mystery of the number 27
– 27 is the smallest evil cube

As Tonya suggests, “Enter a number and I’ll tell you everything you wanted to know about it but were afraid to ask.”

As we worry about running out of fingers and toes, we might recall that it was on this date in 1912 that The Girl Scouts were born in the U.S., as Juliette “Daisy” Gordon Low (who’d met and been deeply influenced by Scouting founder Robert Baden-Powell in London) organized the first Girl Scout troop meeting of 18 girls in Savannah, Georgia.  The annual sale of cookies as a fund-raiser began in 1917.
