The distance has to be less than 10^{15} , but not zero. Otherwise {2,8,72} and {32,50} were a simple solution.

Well, it can even be {1} and {1}, because nobody said they should be different.

If you are asking just to question the simple answer we can go with {2} and {2}.
If you are really asking, then we can use the definition on Wikipedia page on "Smooth Number"s which defines it as: "A positive integer is called Bsmooth if none of its prime factors is greater than B." As none of 1's prime factors are greater than 1, it is Nsmooth for any N > 1.
