I00039 亲密数(Amicable numbers) 一个正整数a的所有正因子之和等于b,b的所有正因子之和等于a,其中因子包括1但不包括本身,且a不等于b,则称a,b为亲密数对。 问题描述:输入n(n为int类型),计算输出≤n的所有亲密数对,亲密数对的两个数用“..”连接,例如:220..284,每个亲密数对之间用空格隔开,输出在一行...
Programming Languages: Scripts written in languages like Python or Mathematica can automate the process of finding and verifying amicable pairs. Databases: Extensive lists of known amicable numbers are maintained in mathematical databases, aiding researchers in their studies.Deficient...

Interestingly the sum of the proper divisors of 220 is 284 and the sum of the proper divisors of 284 is 220, forming a chain of two numbers. For this reason, 220 and 284 are called an amicable pair. Perhaps less well known are longer chains. For example, starting with 12496, we form...
