WebCalculator to calculate the set of all divisors of given natural number. Divisor of numbers is meant integer that divides the number without a remainder. WebJun 26, 2012 · It's factors are 1, 5, 7, 25, 35, 49, 175, 245, 1225 and the sum of factors are 1767. A simple algorithm that is described to find the sum of the factors is using prime factorization. 1225 = 5 2 ⋅ 7 2, therefore the sum of factors is ( 1 + 5 + 25) ( 1 + 7 + 49) = 1767. But this logic does not work for the number 2450. taxi kurdi kempen https://tfcconstruction.net
