To find the first quartile (Q1), you need to follow these steps:

1. First, arrange the data in ascending order: 8, 10, 13, 17, 128.
2. Then, find the median of the whole set of numbers. Since there are 5 numbers, the median is the middle number, which is 13.
3. The first quartile (Q1) is the median of the lower half of the data. In this case, the lower half is 8, 10. The median of these two numbers is the average of 8 and 10, which is 9.

So, the first quartile (Q1) is 9.
