Come on mate, one hundred men FFS. As you say, no way is a gorilla ten times stronger than a powerful man in most functional strength feats and they are what, two to two and half times the size of a well sized man. No mistake about it though, two or three men are sacrificial lambs, they have huge canine teeth and massive jaw power, enough to cause horrifica damage to anything it sinks it's teeth in to. But, ten good men would overwhelm it and stamp it to death IMO.
