I have a group of 4 numbers x,y,z,w which comes from 4 integers multiplied with a common factor. [x,y,z,w] = c [i,j,k,l]. How can I find i,j,k,l?
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...
