Digital ProductMath brain teasers require computations to solve.
The digital product (i.e. product of all its digits) of a positive integer equals the cube of a two-digit integer.
What's the minimal value of the original number?
HintIf you think it's 5558, then you're missing something.
AnswerIt must have 4 digits. If the product is 1000, it's at least 5558.
The product can't be 11^3 because 11 is prime.
But if the product is 12^3, the least number is 3889.
