Divisor Sum of 31,695,652,275

Example of Divisor Sum of Integer

 * $\map {\sigma_1} {31 \, 695 \, 652 \, 275} = 64 \, 795 \, 852 \, 800$

where $\sigma_1$ denotes the divisor sum function.

Proof
We have that:
 * $31 \, 695 \, 652 \, 275 = 3 \times 5^2 \times 7 \times 19 \times 53 \times 167 \times 359$

Hence from Divisor Sum of Integer:
