Proposition: Prop. 8.17: Number does not divide Number iff Cube does not divide Cube
(Proposition 17 from Book 8 of Euclid's “Elements”)
If a cube number does not measure a(nother) cube number then the side (of the former) will not measure the side (of the latter) either. And if the side (of a cube number) does not measure the side (of another cube number) then the (former) cube (number) will not measure the (latter) cube (number) either.
 For let the cube number $A$ not measure the cube number $B$.
 And let $C$ be the side of $A$, and $D$ (the side) of $B$.
 I say that $C$ will not measure $D$.
 And so let $C$ not measure $D$.
 I say that $A$ will not measure $B$ either.
