If d(a) = b and d(b) = a, where a b, then a and b are an amicable pair and each of a and b are called amicable numbers.For example, the proper divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, \u2026","url":"https://jeneshicc.hatenadiary.org/entry/20081028/1225196773","categories":["Project Euler"],"published":"2008-10-28 21:26:13","provider_name":"Hatena Blog"}
