### Amicable Numbers

Amicable numbers are two different numbers related in such a way that the sum of the proper divisors of each is equal to the other number, such as 220 and 284. The Amicable Numbers projects works to find new amicable number pairs. There is currently no known use for these pairs (besides cute necklaces), but who knows what might they might be used for in the future!
