According to the meaning of the question, except 5 and 1, all can be converted into multiples of 4. The minimum number is 16. Then we'll go back from last time.

Last time:16 ...........16/5 = 3 ...1However, the fifth person has taken his share, and he has four copies left. He took four and gave one back to the monkey. That is, it originally had 16+5=2 1. The fifth person saw 2 1. Using the above method, we can quickly calculate that the fourth person sees 26, the third person sees 3 1 and the second person sees 36, so the person with 1 sees 4 1.

Reduction: 1 person 4 1/5 = 8... 1, second person 36/5 = 7... 1, third person 3 1/5 = 6... 1.

The fifth person 2 1/5 = 4... 1 last time 16/5 = 3... 1.
