The Topple Weapon Mastery + Trip Attack + Shield Master

So, if I have a sword and shield Battle Master and I hit an enemy with a Trident that has the Topple Weapon Mastery, which requires a CON saving throw to avoid being knocked Prone, and I also combine Trip Attack to that, which requires a STR saving throw to avoid being knocked Prone, and then I use Shield Master as a Bonus Action which would require another STR saving throw to avoid being knocked Prone, does that mean I could have three attempts at knocking an enemy Prone on my turn?

I know that I can only knock an enemy Prone once, I just want to confirm that I could get three attempts at knocking the enemy Prone on my turn?

TIA

Reading the question, I was thinking "Mmm... I think I saw a similar topic some days ago": Trip Attack + Topple Weapons/ Topple Mastery - Rules & Game Mechanics 

It was also created by you, but this new thread has a new twist :D

BTW, I agree with @wagnarokkr.

 LOL Yeah, I am trying to plan out the Feats I take at Level 6 and Level 8 and Shield Master is one of my considerations. I wonder if forcing three saving rolls per turn to try and knock an enemy Prone is overkill. I am also considering things like Charger, Sentinel, and Heavy Armor Master.

Great memory! :)

 I'd say you're using the rules wisely ;)
