Find all of the primitive roots of p = 89 (recall that we defined primitive roots to be certain integers strictly between 0 and n). Enter the sum of all primitive roots, i.e., if are all of the primitive roots of n, enter 91, 92, 9m .... 91929m below. Hints: • 2 is not a primitive root of any prime p≥ 3 such that p = 1,7 (mod 8). • 3 is not a primitive root of any prime p≥ 5 such that p = (-1) (p-1)/2 (mod 3). • 5 is not a primitive root of any prime p≥ 7 such that p = 1 (mod 5). • 7 is not a primitive root of any prime p≥ 11 such that p = (-1) (p-1)/2 (mod 7).

Find all of the primitive roots of p = 89 (recall that we defined primitive roots to be certain integers strictly between 0 and n). Enter the sum of all primitive roots, i.e., if
91,92,..., 9m
are all of the primitive roots of n, enter
below.
Hints:
91 +92 +
+9m
• 2 is not a primitive root of any prime p≥ 3 such that p = 1,7 (mod 8).
• 3 is not a primitive root of any prime p > 5 such that p = (-1)-1)/2 (mod 3).
• 5 is not a primitive root of any prime p≥ 7 such that p = 1 (mod 5).
• 7 is not a primitive root of any prime p > 11 such that p = (-1)(-1)/2 (mod 7).
