Proposition: 7.35: Least Common Multiple Divides Common Multiple
(Proposition 35 from Book 7 of Euclid's “Elements”)
If two numbers (both) measure some number then the least (number) measured by them will also measure the same (number).
* For let two numbers, $A$ and $B$, (both) measure some number $CD$, and (let) $E$ (be the) least (number measured by both $A$ and $B$).
* I say that $E$ also measures $CD$.
Modern Formulation
see least common multiple.
