# How to Find the Least Common Multiple (LCM) of 8 and 12: Start with Prime Factorizations Understanding the least common multiple (LCM) of two numbers is essential in math, especially in areas like fractions, scheduling, and problem-solving. If you're wondering how to find the LCM of 8 and 12, the most efficient method begins with prime factorization. In this SEO-friendly guide, we’ll walk through the step-by-step process using the prime factorizations of 8 and 12 to clearly explain how to calculate their LCM. ## Why Prime Factorization Matters for LCM The least common multiple of two integers is the smallest positive number that is evenly divisible by both. While listing multiples works, it becomes inefficient with larger numbers. Prime factorization offers a systematic and reliable approach based on the unique prime numbers that make up each factor.
