WebJul 28, 2012 · 7 Answers Sorted by: 61 First, your code should have the condition of i <= n/2, otherwise it can miss one of the factors, for example 6 will not be printed if n=12. Run the loop to the square root of the number (ie. i <= sqrt (n)) and print both i and n/i (both will be multiples of n). WebJul 16, 2024 · Once you have the prime factorization of a number, say. n = p 1 n 1 ⋅ p 2 n 2 ⋯ p r n r, then any positive divisors d of n can be written as. d = p 1 x 1 ⋅ p 2 x 2 ⋯ p r x …

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. michael jackson lowest note

WebSep 21, 2008 · So, one possible algorithm would be: factor (N) divisor = first_prime list_of_factors = { 1 } while (N > 1) while (N % divisor == 0) add divisor to list_of_factors N /= divisor divisor = next_prime return list_of_factors. It is then up to you to combine the factors to determine the rest of the answer. Share. WebJan 2, 2012 · Write a function, divides :: Int -> Int -> Bool such that. x `divides` n. is true when x is a divisor of n. So, first, think about what it means for x to be a divisor of n. Now that you have a way to check if a single number x is a divisor of n, you need to check a certain range of numbers less than n to see which ones are divisors. Hint: In ... WebOct 24, 2024 · Explanation: Here P = 21 * 30 * 15 * 24 * 16 = 3628800. Distinct prime divisors of 3628800 are 2, 3, 5 and 7. So, the output is 4.
