I am given nine values for oildroplets, like in Millikan's experiment, and using that data I have to find the number of electrons in each droplet and the charge on the electron.
The values for the droplets go something like this: 6.563E-19 C, 8.204E-19 C, 11.50E-19 C.
Is there an equation that I need to use to solve this problem, and if not then what should I do?

Find the common factor.
