Divisor Sum of 29,912,035,725

Example of Divisor Sum of Integer

 * $\map {\sigma_1} {29 \, 912 \, 035 \, 725} = 64 \, 795 \, 852 \, 800$

where $\sigma_1$ denotes the divisor sum function.

Proof
We have that:
 * $29 \, 912 \, 035 \, 725 = 3^3 \times 5^2 \times 11 \times 13 \times 431 \times 719$
