WebMar 24, 2024 · A divisor, also called a factor, of a number n is a number d which divides n (written d n). For integers, only positive divisors are usually considered, though obviously the negative of any positive divisor is itself a divisor. A list of (positive) divisors of a given integer n may be returned by the Wolfram Language function Divisors[n]. Sums and … WebMar 4, 2024 · Given a positive integer N, the task is to find the sum of divisors of all the numbers from 1 to N. Examples: Input: N = 5 Output: 21 Explanation: Sum of divisors of all numbers from 1 to 5 = 21. Divisors of 1 -> 1 Divisors of 2 -> 1, 2 Divisors of 3 -> 1, 3 Divisors of 4 -> 1, 2, 4 Divisors of 5 -> 1, 5, hence Sum = 21

WebNov 23, 2024 · Efficient Solution: We can observe that the number of divisors is odd only in case of perfect squares. Hence the best solution would be to check if the given number is perfect square or not. If it’s a perfect square, then the number of divisors would be odd, else it’d be even. CPP. #include .
