4. (6 points) There is a plate of fruit, when counted 3 at a time, 2 are left; when counted 4 at a time, 3 are left; when counted 5 at a time, 4 are left; when counted 6 at a time, 5 are left. The plate has at least $\qquad$ fruits.
【Answer】Solution: Since $3=1 \times 3, 4=2 \times 2, 5=1 \times 5, 6=2 \times 3$, there are at least:
$$
\begin{array}{l}
3 \times 2 \times 2 \times 5-1 \\
=60-1 \\
=59 \text{ (pieces). }
\end{array}
$$

Answer: There are at least 59 pieces of fruit in this plate.
Therefore, the answer is: 59.
