Well...I could multiply by (1/25) and that would give us

33275 *(1/25) = 1331 and that's a perfect cube of 11

Or...I could multiply by 0   and that would give us

33275 * 0 = 0    and that's the perfect cube of 0

Or...I could multiply by -5 and that would give us

-166375 and that's a perfect cube of (-55)

Is this what you were asking??.....Is there a "smallest" number??

First look at the prime factors of 33275

factorize(33275){25=521331=113}

i.e. 33275=52113

This should give you a clue.

I suspect the questioner had positive integers in mind!
