The first common multiple between 100, 25, and 10, is 100.

This means that the first customer that receives the 3 prizes is the 100th customer.

<h3>What customer will be the first to receive all 3 prizes?</h3>

Here we know that:

The first customer that gets the 3 prizes is a customer that is a 10th customer, a 25th customer, and a 100th customer at the same time.

Then we need to find the first common multiple between 10, 25, and 100.

This is really trivial, as we know that:

10*10 = 100

So 100 is a multiple of 10.

25*4 = 100

So 100 is a multiple of 25.

Then the first common multiple between 100, 25, and 10, is 100.

This means that the first customer that receives the 3 prizes is the 100th customer.
