Analysis: According to the stem analysis, everyone picked the same number of peaches, all less than 100. Subtract 1 from the number of peaches picked by each person, which is the common multiple of 3, 4 and 5, and you can answer the question.

Answer: According to the stem analysis, it can be concluded that the number of peaches picked by everyone is the same, which is less than 100.

The number of peaches picked by each person minus 1 is exactly the common multiple of 3, 4 and 5.

Because the smallest common multiple of 3, 4 and 5 is 3×4×5=60, and the larger common multiple is 60×2= 120, which is beyond 100, which does not meet the meaning of the question.

So the number of peaches picked by each person is 60+ 1=6 1 (one).

A: Everyone picked 6 1 peach.
