Review Questions
Explain how the Fundamental Theorem of Arithmetic relates to the process of prime factorization.
The Fundamental Theorem of Arithmetic states that every positive integer greater than 1 can be expressed as a unique product of prime numbers. This means that when performing prime factorization, the prime factors used and their exponents will always be the same, regardless of the order in which they are written. This unique prime factorization is essential for understanding the properties of numbers and solving problems involving factors, multiples, and the least common multiple.
Describe the role of the Fundamental Theorem of Arithmetic in finding the least common multiple (LCM) of two or more numbers.
The Fundamental Theorem of Arithmetic is crucial for determining the least common multiple (LCM) of two or more numbers. Since the prime factorization of a number is unique, the LCM can be found by taking the product of the highest power of each prime factor present in the prime factorizations of the given numbers. The Fundamental Theorem of Arithmetic ensures that this process will always yield the smallest positive integer that is divisible by all the given numbers, making it an essential tool for solving problems involving the LCM.
