You find the LCM of 6 and 10.

First, do their prime factorizations.

6 = 2 times 3                                10 = 2 times 5

The 2 factorizations have 2 in common, so you take what they have in common and multiply it by what they don't have in common.

The LCM is 2 times 3 times 5, which is 30.

The 30th customer is the first to get both a free T-Shirt and a free water bottle.

I want to be the 30th customer! :)
