# Math Help - Hasse diagram ?

1. ## Hasse diagram ?

Hi folks, I just wanted to "check my answers" -
here is a poset ({2,4,6,9,12,18,27,36,48,60,72},|)
that's "|" is divide (divisibility)

1) upper bound of {2,9}
2)least upper bound of {2,9}

3)lower bounds of {60,72}
4)greatest lower bound of {60,72}

I wish Soroban knew some discrete math. He seems to be a nice guy!

2. i'll give it a try..
