Example of Triperfect Number

$1 \, 476 \, 304 \, 896$ is triperfect:

$\sigma \left({1 \, 476 \, 304 \, 896}\right) = 4 \, 428 \, 914 \, 688 = 3 \times 1 \, 476 \, 304 \, 896$


Proof

From $\sigma$ of $1 \, 476 \, 304 \, 896$:

$\sigma \left({1 \, 476 \, 304 \, 896}\right) = 4 \, 428 \, 914 \, 688$

Hence the result.
