This exercise will show by example how to use the results of Exercise 20 to prove a number is a primitive root mod a prime p, once we know the factorization of p  1. In particular, well show that 7 is a primitive root mod C01. Note th at 600 = 23 – 3  52.    (a) Show th at if an integer r < 600="" divides="" 600,="" then="" it="" divides="" at="" least="" one="" of="" 300,="" 200,="" 120="" (these="" numbers="" are="" 600/2,="" 600/3,="" and="" 600/5).   ="" (b)="" show="" that="" if="" ordcoi(7)="">< 600,="" then="" it="" divides="" one="" of="" the="" numbers="" 300,="" 200,="">
