packs of the same number of bottles.

What is the greatest number of bottles

that could be in a pack?

Step-by-step explanation:

This is a way of asking you what the highest common factor is. So factor into primes and find the highest that is between them.

48: 2 * 2 * 2 * 2 * 3

60: 2 * 2 * 3 * 5

The answer is Bolded and underlined.

HCF: 2 * 2 * 3

The greatest number that could be in a pack is 12
