Example of Sigma Function of Integer

 * $\sigma \left({154 \, 345 \, 556 \, 085 \, 770 \, 649 \, 600}\right) = 926 \, 073 \, 336 \, 514 \, 623 \, 897 \, 600$

where $\sigma$ denotes the $\sigma$ function.

Proof
We have that:
 * $154 \, 345 \, 556 \, 085 \, 770 \, 649 \, 600 = 2^{15} \times 3^5 \times 5^2 \times 7^2 \times 11 \times 13 \times 17 \times 19 \times 31 \times 43 \times 257$

Hence:
