The common factor must be an integer too, or else there is no way to find it without more parameters; defining the step and search interval for instance. Currently, any multiple of 5 would produce a valid "restored vector" for the only available test. The problem also needs a better test suite. It's a good problem.

Doesn't always work, for example when x = 11*[ 5, 7, 32] .

Oops. C itself doesn't have to be an integer. Should have checked the test suite more carefully...
