Determine ?(????) using Euler’s totient function
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
So there are 720 number of positive integers that are less than 2700 which are co-primes of 2700 is present.
