| Aug 10, 2023 at 21:39 | comment | added | Steven Creech | Good catch, so the general formula for square-free should be $\frac{\sigma(n)}{2^k}-1$ | |
| Aug 10, 2023 at 19:30 | comment | added | Erick Wong | Since this is the squarefree case, it happens that $\prod (p+1)$ can be identified with the sum of divisors function $\sigma(n)$, though this isn't true in general. | |
