Amicable Triplet/Examples/103,340,640-123,228,768-124,015,008

Example of Amicable Triplet
The following numbers form an amicable triplet:
 * $103 \, 340 \, 640$
 * $123 \, 228 \, 768$
 * $124 \, 015 \, 008$

Proof
Let $\map s n$ denote the aliquot sum of $n$.

By definition:
 * $\map s n = \map \sigma n - n$

where $\map \sigma n$ denotes the $\sigma$ function.

Thus:
