Example of Divisor Sum of Integer
- $\map {\sigma_1} {48 \, 976} = 94 \, 922$
where $\sigma_1$ denotes the divisor sum function.
Proof
We have that:
- $48 \, 976 = 2^4 \times 3061$
Hence:
\(\ds \map {\sigma_1} {48 \, 976}\) | \(=\) | \(\ds \frac {2^5 - 1} {2 - 1} \times \paren {3061 + 1}\) | Divisor Sum of Integer | |||||||||||
\(\ds \) | \(=\) | \(\ds 31 \times 3062\) | ||||||||||||
\(\ds \) | \(=\) | \(\ds 31 \times \paren {2 \times 1531}\) | ||||||||||||
\(\ds \) | \(=\) | \(\ds 94 \, 922\) |
