$118$


Mistake

$118$ is the smallest number which can be written as the sum of four triples, whose products are all equal: $118 = 14 + 50 + 54 = 15 + 40 + 63 = 18 + 30 + 70 = 21 + 25 = 72$.
The product of each triple is $37,800$. [Mauldron, Guy, 172]


Correction

That first name should read Mauldon.

It appears that this most probably refers to J.G. Mauldon, who published similar results for $5$ such triples as a problem in American Mathematical Monthly in $1981$.
