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

Example of Integers Differing by 2 with Same Sigma
Let $\sigma: \Z_{>0} \to \Z_{>0}$ denote the $\sigma$ function: the sum of all the positive integer divisors of $n$.

Then:
 * $\sigma \left({366}\right) = \sigma \left({368}\right) = 744$

Proof
From :
 * $\sigma \left({366}\right) = 744$

From :
 * $\sigma \left({368}\right) = 744$

Hence the result.
