Mathematics may not deal in disputed definitions, but Wikipedia certainly does.

That would be 3:
2 multiplied by itself is 4. No matter if you do it once or 57,885,160 times. Then minus one.
Or it could be 4 if you only do it 57,885,159 times. But I think 4 is not a prime number.

I can't speak for other people, but I often use (2^57,885,161)-1 in casual conversation.
