In an experiment to measure the charge on an electron, the following values of charge were found on oil droplets: `-1.6 xx 10^(-15), -2.4 xx 10^(-19),-4.0 xx 10^(-19)` (in coulomb). What values of electronic charge would be indicated by these results?

Explanation

Find the largest common factor.
`-0.8 xx 10^(-19)C `
