$2^2 \times 3^2 \times 11^2$


The sum of the first $11$ cubes:
$4356 = 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3 + 10^3 + 11^3$

$4356 = \map {\sigma_1} {1782} = \map {\sigma_1} {2410} = \map {\sigma_1} {2902} = \map {\sigma_1} {4097}$


The $66$th square number after $1$, $4$, $9$, $16$, $25$, $36$, $\ldots$, $3249$, $3364$, $3481$, $3600$, $3721$, $3844$, $3969$, $4096$, $4225$:
$4356 = 66 \times 66$
