examples of smooth numbers

If a number is $k$-smooth, it is also a smooth number for smaller $k$. So, to give just a handful of examples of smooth numbers for a few different values of $k$, the following table only goes up to 100, and for $k>2$, only those numbers not already listed for smaller $k$ are given. Also, the $k$ have been limited to prime numbers. Obviously the 2-smooth numbers are the powers of two.
