Quasiamicable Numbers/Examples/1575,1648

Examples of Quasiamicable Pair

$1575$ and $1648$ form a quasiamicable pair.

Proof

\(\ds \map {\sigma_1} {1575}\)

\(=\)

\(\ds 3224\)

$\sigma_1$ of $1575$

\(\ds \map {\sigma_1} {1648}\)

\(=\)

\(\ds 3224\)

$\sigma_1$ of $1648$

\(\ds 1575 + 1648 + 1\)

\(=\)

\(\ds 3224\)

Hence the result by definition of quasiamicable pair.
