Question

what is the largest number with which the product of any three consecutive multiples of 3 can be divided exactly

Answer 1

The charge of the electron is equivalent to the magnitude of the elementary charge (e) but bearing a negative sign. Since the value of the elementary charge is roughly 1.602 x 10-19coulombs (C), then the charge of the electron is -1.602 x 10-19 C.

Answer 2

72 is the largest no.
