Best ResponseYou've already chosen the best response.0I started working with a smaller number for simplicity, such as 136. 1. Make a list of all divisors of the number. 136 = 2^3 * 17 > 8 divisors {1, 2, 4, 8, 17, 34, 68, 136} 2. Now that we have a list of divisors, let's begin to sort out all the composite factors. How do we do that? Well, we first remove 1 from the set of divisors \(S\) and call that \(S'\). Now, a composite factor here would be one that can be expressed as the product of elements in \(S'\). We remove all those. How? We create a set of all such products. And then we remove the common elements from \(S'\) and get a list of prime factors.
