Therefore, 220 and 284 are amicable numbers.Additional Examples of Amicable NumbersAmicable numbers are relatively rare, especially as numbers grow larger. Here is a list of known amicable pairs:220 284 1184 1210 2620 2924 5020 5564 6232 6368 10744 10856 12285 14595... ...437456 455344...
The meaning of AMICABLE NUMBER is either of a pair of numbers each of which equals the sum of the different exact divisors of the other excluding the number itself.
Fermat used this sequence in 1636 to generate the pair of amicable numbers (17,296 and 18,416). Descartes used this sequence in 1638 to find the pair (9,363,584 and 9,437,056). Euler created additional methods and published a list of 30 new amicable number pairs in 1747, and later ...
