#### Answer

$6.40*10^{-13}$ zirkombs.

#### Work Step by Step

We divide each of the charges by the smallest charge to find: $$\frac{2.56*10^{-12}}{6.40*10^{-13}}=4$$ $$\frac{7.68*10^{-12}}{6.40*10^{-13}}=12$$ $$\frac{3.84*10^{-12}}{6.40*10^{-13}}=6$$ $$\frac{6.40*10^{-13}}{6.40*10^{-13}}=1$$ Because $6.40*10^{-13}$ produced the smallest integer value, the charge of electron is $6.40*10^{-13}$ zirkombs.
