Answer 1

Answer:

Example of Amicable Pair

220 and 284 are the smallest amicable pair:

σ(220)=σ(284)=504=220+284

Proof

Let s(n) denote the aliquot sum of n.

By definition:

s(n)=σ(n)−n

where σ(n) denotes the σ function.

Thus:

s(220) = σ(220)−220

= 504−220 σ of 220

= 284

s(284) = σ(284)−284

= 504−284 σ of 284

= 220

It can be determined by inspection of the aliquot sums of all smaller integers that there is no smaller amicable pair.
