Question is completely unrealistic and illogical. Black bears are not pack-oriented animals and will not bond together to bring down or kill any animal, including a grizzly bear. Thus how many black bears? None, because the fight can or will never happen.
It will take 20 small dogs to kill a bear, and 5 large dogs to kill a bear.

A bear can only kill a human once, because a person can not be killed twice.
The question is completely unrealistic and illogical. Black bears are not pack-oriented animals like dogs, wolves and lions are, and thus will not work together to bring a polar bear down. They will more often choose to fight each other or run away than attack and attempt to kill a large animal like a polar bear.
