Can you explain why it wont be a lattice? Pick any two elements, they will have a LUB and GLB.

Here, the relation is less than or equal to specifically, right?

and also universal upper bound doesn't exist because natural numbers will go on and on, right? and that's  why it's not complemented lattice, right? please help me, thanks.
