Python Program for Find minimum sum of factors of number
Given a number, find minimum sum of its factors.
Examples:
Input : 12 Output : 7 Explanation: Following are different ways to factorize 12 and sum of factors in different ways. 12 = 12 * 1 = 12 + 1 = 13 12 = 2 * 6 = 2 + 6 = 8 12 = 3 * 4 = 3 + 4 = 7 12 = 2 * 2 * 3 = 2 + 2 + 3 = 7 Therefore minimum sum is 7 Input : 105 Output : 15
# Python program to find minimum# sum of product of number # To find minimum sum of# product of numberdef findMinSum(num): sum = 0 # Find factors of number # and add to the sum i = 2 while(i * i <= num): while(num % i == 0): sum += i num /= i i += 1 sum += num # Return sum of numbers # having minimum product return sum # Driver Codenum = 12print findMinSum(num) # This code is contributed by Sachin Bisht |
Output:
7
