4. Flint has five sailors and 60 gold coins. He wants to distribute them into wallets, and then give the wallets to the sailors so that each gets an equal number of coins. But he doesn't know how many sailors will be alive by the time of the distribution. Therefore, he wants to arrange the coins so that they can be evenly distributed to two, three, four, or five sailors. Will nine wallets be enough for this?
Solution. Yes. For example, with the following number of coins in the wallets: $12,12,8,7,6,5$, $4,3,3$.

Note that a smaller number of wallets is insufficient (see the solution to problem 4 for grade 6).
