WebThe most basic method for computing divisors is exhaustive trial division. If we want to find the positive divisors for an integer n, we just take the integers 1, 2, 3, . . . , n, divide n by each, and those that divide evenly make up the set of positive divisors for n. This method works well and is rather simple, but it is also quite inefficient. gg\u0027s waterfront restaurant
