Final answer:
The Prime Factorization of a set of positive integers allows us to find all the unique prime factors of that set, which is option C in the question provided.
Step-by-step explanation:
The concept we are looking at in the question is related to finding what can give us the unique prime factors of a set of positive integers. The correct option here is C) Prime Factorization. Prime factorization involves breaking down each number in the set into its prime factors, which are the prime numbers that multiply together to give the original number.
Option A, LCM (Least Common Multiple), refers to the smallest number that is a multiple of all numbers in the set. Option B, GCF (Greatest Common Factor), is the largest number that divides all the numbers in the set without any remainder. Lastly, option D, Exponentiation, is related to integer powers and involves raising a number to the power of another number, but it does not reveal the prime factors.
