Not a question  just something I came across in a math book. Amicable Numbers: 220 and 284 are good friends. Why?  well the divisors of 220 are 1,2,4,5,10,11,20,22,44,55 and 110 and if you add them up you get 284. You've guessed it. If you figure out the divisors of 284 and add them up you get 220. Don't expect they are of any practical use but they have been used in compiling romantic horoscopes!
