Web17 jul. 2024 · then any positive divisors d of n can be written as d = p 1 x 1 ⋅ p 2 x 2 ⋯ p r x r where each exponent x i is a non-negative integer less or equal to n i. The number of such divisors is equal to the product ( n 1 + 1) ⋅ ( n 2 + 1) ⋯ ( n r + 1). In your example n = 372 = 2 2 ⋅ 3 1 ⋅ 31 1 and therefore the divisors are 3 ⋅ 2 ⋅ 2 = 12 and they are WebThe totient function phi(n), also called Euler's totient function, is defined as the number of positive integers <=n that are relatively prime to (i.e., do not contain any factor in common with) n, where 1 is counted as being relatively prime to all numbers. Since a number less than or equal to and relatively prime to a given number is called a totative, …
