Amicable pairs	5949b579404977fbaefcd737	5		友好的对

Description

如果$ N \ neq M $和N $ $的适当除数之和（$ \ mathrm {sum}（\ mathrm {propDivs}（N）），两个整数$ N $和$ M $被认为是友好对 $）$ = M $以及$ \ mathrm {sum}（\ mathrm {propDivs}（M））= N $。示例：1184和1210是友好对，具有适当的除数：1,2,4,8,16,32,37,74,148,296,592和1,2,5,10,11,25,55，分别为110,121,242,605。任务：计算并显示低于20,000的Amicable对（有八个）。相关任务适当的除数丰富，缺陷和完善的数字分类等分序列分类及其友好分类。
