| Oct 4, 2017 at 15:28 | comment | added | Gerhard Paseman | 3-smooth numbers are another name for positive integers of the form $2^a3^b$, for integral exponents $a$ and $b$. Divisibility in the natural numbers is a lattice order. Gerhard "Perhaps I Should Say 'Friable'" Paseman, 2017.10.04. | |

| Oct 4, 2017 at 15:25 | comment | added | Dominic van der Zypen | Right - I will delete my remark about the top element. What are smooth numbers? Do they give an example for a lattice as in the question? Thanks! | |
| Oct 4, 2017 at 15:24 | comment | added | Gerhard Paseman | Lattices do not have to have a top element. Consider the 3 smooth numbers under divisibility. Gerhard "Likes General Algebraic Number Theories" Paseman, 2017.10.04. | |
