For a prime number p, all positive integers less than p has no positive factor in common with p other than 1. Hence number of such positive integers, i.e. f(p) = Number of positive integers less than p = (p - 1)trangle wrote:The function f is defined for all positive integers n by the following rule: f(n) is the number of positive integers each of which is less than n and has no positive factor in common with n other than 1. If p is any prime number then f(p)=
a. p-1
b. p-2
c. (p+1)/2
d. (p-1)/2
e. 2
