2 numbers the factor of each adds up to make the other number?
Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number. For example, the smallest pair of amicable numbers is (220, 284)
What is interesting about the factors of 220 and 284?
the factors of 220 add up to 284; the factors of 284 add up to 220. 220 is divisible by 1,2,4,5,10,11, 20,22,44,55 and 110. 1+2+4+5+10+11+20+22+44+55+110 = 284 284 is divisible by 1,2,4,71 and 142. 1+2+4+71+142 = 220. A pair of numbers with this ability is called 'amicable numbers'. Other knows pairs of amicable numbers are (17296, 18416) and (9363584, 9437056).

Who are the famous mathematicians who discovered the amicable numbers?
Pythagoras discovered the smallest pair of amicable numbers: 220 and 284. The Arab mathematician Al-Banna found a larger amicable pair, 17,296 and 18,416, but European mathematicians were not aware of this discovery. Pierre de Fermat rediscovered this amicable pair in 1636. Rene Descartes rediscovered another amicable pair known to Arab mathematicians in 1638 - the pair 9,363,584 and 9,437,056. Leonhard Euler found 30 pairs of amicable numbers by 1747 because he developed a formula that could produce amicable pairs. B. Nicolo I. Paganini found the smaller amicable pair 1184 and 1210 that had been missed by other European mathematicians in 1866.
