Number of divisors formula
WebAmicable numbers are two different numbers related in such a way that the sum of the proper divisors of each is equal to the other number. The smallest pair of amicable numbers is (220, 284). ... For example, the proper divisors of 6 are 1, 2, and 3.) A pair of amicable numbers constitutes an aliquot sequence of period 2. WebExtend the definition to arbitrary divisors in general position by noticing every divisor has a unique expression as D = P – N for some effective divisors P and N. So let Di = Pi – Ni, and use rules of the form to transform the intersection. 5.

Web16 dec. 2024 · The number of natural divisors of the number $n$. This arithmetic function is denoted by $\tau (n)$ or $d (n)$. The following formula holds: $$ \tau (n) = (a_1+1) \cdots (a_k+1) $$ where $$ n = p_1^ {a_1} \cdots p_k^ {a_k} $$ is the canonical expansion of $n$ into prime power factors. WebAn arithmetic function f(n) : N !C is multiplicative if for any relatively prime n;m2N: f(mn) = f(m)f(n): Examples. Let n2N.

Web25 jul. 2024 · Factors of a number any number “ P” refers to all the numbers which are exactly divisible on “P” i.e remainder comes to zero. These factors of numbers are also called divisors of a number. For example: Factors of the number 9. 1 × 9 = 9, Also 3 × 3 = 9; So 1, 3, and 9 are factors of 9. Web9 okt. 2024 · Ques 1 : Find the total number of odd factors of 120. Solution : Prime Factorization of 120 is 120 = 23 × 31 × 51. Thus, Total number of odd factors of 120 is (1 + 1) (1 + 1) = 2 × 2 = 4. Ques 2 : Find the total number of odd factors of 84. Solution : Prime Factorization of 84 is 84 = 22 × 31 × 71.
