That was the total amount of damage to complete all goals last Raid Boss. That means that in a 60 player syndicate, each player had to contribute 6,410,530,959 damage. For RB to be free (no gold spent) each player needed to have a 89,035,153 FA, and needed to have put in that FA every 100 minutes (how long it takes to regen) in the 5 days that RB is live. Seem insane yet? Take a look at these numbers.

Additional math:
To knock down higher level bosses you would need 60 players with an FA of:
L100: 139,043,743
L95: 65,222,139
L90: 25,456,566
L85: 20,268,243
