2 people A and B with a help of a monkey collected many coconuts, got tired and fell asleep. At night A woke up and decided to have his share. He divided coconuts into 2 equal shares giving the left out single coconut to the monkey for its hard labor and fell asleep again. In the same way B woke up and not knowing whether anyone woke up he also divided the coconuts into 2 equal shares, giving the left out single coconut to the monkey. Early in the morning both of them woke up together, divided the coconuts into 2 equal shares and a left out coconut was given to the monkey. What is the minimum number of coconuts that they collected?
