Cody Problem 656 deals with the totient function, denoted by 
which counts the numbers less than n that are relatively prime to n. The first five values of the totient are 1, 1, 2, 2, and 4.
which counts the numbers less than n that are relatively prime to n. The first five values of the totient are 1, 1, 2, 2, and 4. The totient summatory function 
is the sum of the values of 
from 
to n. Therefore, 
.
is the sum of the values of from to n. Therefore, . Write a function to compute the totient summatory function.
