Answer #1

Totient Funtion : Let us consider a number N. Totient function gives the number of positive integers that are less than N that are co-primes to N.

Here P1,P2,P3,..... Pk are the prime factors of N

Given N=2700.

2700= 22.33.52

= 720.

So there are 720 number of positive integers that are less than 2700 which are co-primes of 2700 is present.

I hope I have clearly explained the procedure with calculation. If you want you can try with other examples as well. If you find any difficulties please feel to comment. I will be available to solve your quires. Please support by upvote if you like my presentation and explanation.

Euler's Totient Function Let f(n) denote Euler's totient function; thus, for a positive integer n, f(n) is the number of integers less than n which are coprime to n. For a prime p its is known that f(p^k) = p^k-p^{k-1}. For example f(27) = f(3^3) = 3^3 - 3^2 = (3^2) 2=18. In addition, it is known that f(n) is multiplicative in the sense that f(ab) = f(a)f(b) whenever a and b are coprime. Lastly, one has the celebrated generalization...
