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

As well as {25} and {9, 4}

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

Is 1 a smooth number?

[QUOTE=Dieter;518425]Is 1 a smooth number?[/QUOTE]
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 "[URL="https://en.wikipedia.org/wiki/Smooth_number"]Smooth Number[/URL]"s which defines it as: "A positive integer is called B-smooth if none of its prime factors is greater than B." As none of 1's prime factors are greater than 1, it is N-smooth for any N > 1. |
