**Steve**, Wednesday, February 27, 2013 at 12:47pmsounds like you want a perfect square. Any other kind of number will have at least 4 factors: 1,n,q, and n/q or be a prime, with only 2 factors.

So, what's the largest square n <= 9999?

√9999 = 99.99, so

99^2 = 9801 has just 3 factors: 1,99,9801

64 = 8^2 = 4^3

1729 = 1^3 + 12^3 = 9^3 + 10^3

It is the smallest number which can be expressed as the sum of two cubes in two different ways.
