Find divisors of a number in java
WebJun 23, 2024 · Given a natural number, calculate sum of all its proper divisors. A proper divisor of a natural number is the divisor that is strictly less than the number. For example, number 20 has 5 proper divisors: 1, 2, 4, 5, 10, and the divisor summation is: 1 + 2 + 4 + 5 + 10 = 22. Input : num = 10 Output: 8 // proper divisors 1 + 2 + 5 = 8 Input : num ...

For example, in the case of 6, initialize sum = 1, because 1 will be always part of the sum, and then when you see 2, also add 6 / 2 to the sum. (You can get sqrt with #include "math.h" .)
WebExample 1. Find the divisors of number 12. First, one is a divisor of any number. Let us also have the first divisor of 12 be 1. Now decompose the number 12 into prime factors: We obtained the decomposition 2 × 2 × 3. In the process of decomposition of number 12 into prime factors, we divided it into numbers 2 and 3.
WebNumber of divisors; Sum of divisors; Problem statement. A Composite number is a number greater than 1 with more than two factors. A Divisor is a number that divides another number either completely or with a remainder. So, given a number N, we have to find: Sum of Divisors of N; Number of Divisors of N; 1.
