Any integer n can be uniquely factored in prime numbers:

n = 2^(a)*3^{b}*5^{c}*...

If an integer is a square then all the exponents a, b, etc. must be even. If it is a cube they must all be divisible by 3. If the integer is required to be a cube and a square then the exponents must be divisible by six.

The smallest solution is obtained, obviously, by choosing all the exponents equal to zero, which yields n = 1. The next largest is obtained for a = 6 and b =c =...=0, which yields n = 64.
