16. There are five sailors and a monkey on a small island. During the day, they collected some coconuts as food. At night, one of the sailors woke up and decided to take his share of the coconuts. He divided the coconuts into five equal parts, with one left over, so he gave the extra one to the monkey and hid his share, then went back to sleep. After a while, the second sailor woke up and did the same thing. When he divided the remaining coconuts into five equal parts, there was also one left over, which he gave to the monkey, and then he hid his share and went back to sleep. The other three sailors also did the same thing in turn. The next morning, they woke up and pretended nothing had happened, dividing the remaining coconuts into five equal parts, with none left over. How many coconuts were there originally, and how many coconuts did each of them get in total?
16. This pile of coconuts has at least 3121. The number of coconuts each of the five people received in turn is $828, 703, 603$, 523, 459, and the monkey ate 5.
