No.

One gorilla VS. 31 men = 31 dead and critically injured men.

There is nothing you or 30 of your closest buddies could do to hurt a full-grown gorilla.

Gorilla’s skulls are too dense and thick for any of your strikes to affect him. A head kick from the hardest kicker in the world, Mirko Cro Cop, would damage his leg more than the gorilla’s head.

Gorillas are built to withstand the rigors of living in the wild, which includes fighting other gorillas. You would be going against an experienced heavyweight champion in a fight you haven’t trained for.

Once that gorilla feels you and your friends are a threat, he will tear through each of you individually as if you were paper dolls.

He is strong enough to break your bones with a strike from his massive and lightning-fast hands, or he could snap your bones by squeezing you in his bone crushing grip. He can pull all your limbs from out of socket leaving you disabled, or he just could rip them off your body completely if he chose to.

The worst and most effective move he has at his disposal is the ability to bite you with his massive fanged gorilla bite. Imagine the regret you and your 30 friends will have for not initially running away from this fight as you witness this lone gorilla quickly tearing large chunks of flesh from your bodies before any of you have time to react.

The fight scenario you proposed would end with 31 dead and broken bodies lying on the ground, while the gorilla beats his chest in triumph like King Kong.
