Finding divisors of a number
WebJul 17, 2024 · 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 2 0 ⋅ 3 0 ⋅ 31 0 2 0 ⋅ 3 0 ⋅ 31 1 2 0 ⋅ 3 1 ⋅ 31 0 WebApr 11, 2024 · Given a number n, the task is to find the odd factor sum. Examples : Input : n = 30 Output : 24 Odd dividers sum 1 + 3 + 5 + 15 = 24 Input : 18 Output : 13 Odd dividers sum 1 + 3 + 9 = 13 Recommended: Please try your approach on {IDE} first, before moving on to the solution.
