Let there be  a polygon with minimum number of sides i.e. 3.

Exterior angles a equilateral triangle has maximum measure.

Sum of exterior angles of polygon = $360\degree$

Let exterior angle be A.

$\therefore$           $A+A+A=360\degree$

$3\ast A=360\degree$

$A=120\degree$

Hence,the maximum exterior angle possible for a regular polygon is $120\degree$.
