**Draw hasse diagram representing the positive divisor of 36 and show digraph to It?**

The **Answer to the Question**

is below this banner.

**Here's the Solution to this Question**

a divides a so the relation R is reflexive. If $a,b$ are positive integers then, if $a|b$ then clearly, $b\nmid a$ . Hence the relation is not symmetric. Now $a|b\Rightarrow b=ax$ for some integer $x.$ Again $b|c\Rightarrow c=by$ for some integer y. Hence $c=axy$ and so $a|c.$ Hence the relation is transitive. So the relation is a partial order relation and the set is a poset. Also its not totally ordered since 4,9 are non comparable.

Now its not a lattice since $4\vee 9$ doesn't exist. since their least upper bound must be divisible by both 4 and 9 and no such element exist.
