Divisor Sum of 51,001,180,160

Example of Divisor Sum of Integer

 * $\map {\sigma_1} {51 \, 001 \, 180 \, 160} = 153 \, 003 \, 540 \, 480$

where $\sigma_1$ denotes the divisor sum function.

Proof
We have that:
 * $51 \, 001 \, 180 \, 160 = 2^{14} \times 5 \times 7 \times 19 \times 31 \times 151$

Hence:
