Which is an example of sum of factors?
Example 1: Find the number of co-primes to 90 that are less than 90. Example 2: Find the sum of all the co-prime numbers to 90 and less than 90. Write the number in prime factorization format N = apbqcr ….. We know that number of factors of N is given by n ( F )= ( p + 1) ( q + 1) ( r + 1). Let us understand this by taking one example.
Which is the sum of factors less than n?
The number of co-primes to number n and also less than n is given by . This is also denoted by n (1− 1 a) (1− 1 b) (1− 1 c) n ( 1 − 1 a) ( 1 − 1 b) ( 1 − 1 c) N (o) Euler’s totient. And sum of all these co-primes are given by N × N (Ø)= n2 2 (1− 1 a) (1− 1 b) (1− 1 c) n 2 2 ( 1 − 1 a) ( 1 − 1 b) ( 1 − 1 c) ……..
