Integers Differing by 2 with Same Divisor Sum/Examples/366

Example of Integers Differing by 2 with Same Divisor Sum

Let $\sigma_1: \Z_{>0} \to \Z_{>0}$ denote the divisor sum function.

Then:

$\map {\sigma_1} {366} = \map {\sigma_1} {368} = 744$

Proof

From $\sigma_1$ of $366$:

$\map {\sigma_1} {366} = 744$

From $\sigma_1$ of $368$:

$\map {\sigma_1} {368} = 744$

Hence the result.
