ANSWER


16\text{ bags}

Step-by-step explanation

We want to find the number of bags that he can make without having any leftovers.

To do this, we have to find the highest common factor of the numbers of the two flavors of cookies, i.e. 48 and 64.

To do that, express both numbers as products of their prime factors and pick only the numbers that are common among them:

48 = 2 * 2 * 2 * 2 * 3

64 = 2 * 2 * 2 * 2 * 2 * 2

The boldened numbers are the common ones so, the highest common factor is:


\begin{gathered} \text{HCF}=2\cdot2\cdot2\cdot2 \\ \text{HCF}=16 \end{gathered}

Therefore, George can make 16 bags without having any leftovers.
