[ Divisibility of numbers. General properties ]

On a sunken caravel from the 14th century, six bags of gold coins were found. In the first four bags, there were 60, 30, 20, and 15 gold coins. When the coins in the remaining two bags were counted, someone noticed that the number of coins in the bags formed a certain sequence. Taking this into account, could you say how many coins are in the fifth and sixth bags?

#
Note: All numbers $60,30,20,15$ are divisors of the number 60.

## Solution

The number of coins in these bags are the divisors of the number 60, listed in descending order. So, in the fifth and sixth bags, there are 12 and 10 gold coins, respectively.

## Answer

12 and 10 coins.
