Understanding the Least Common Multiple of 8 and 12

In mathematics, understanding the concept of least common multiple is crucial for solving various problems and equations. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. In this article, we will explore the process of finding the LCM of 8 and 12, and understand its significance in mathematics.

Finding the Factors of 8 and 12

Before we delve into finding the LCM of 8 and 12, let’s first identify the factors of each number. The factors of 8 are 1, 2, 4, and 8. Similarly, the factors of 12 are 1, 2, 3, 4, 6, and 12.

Identifying the Common Factors

Next, we identify the common factors between 8 and 12. The common factors of 8 and 12 are 1 and 2.

Finding the Least Common Multiple

To find the LCM of 8 and 12, we can use the concept of prime factorization.

Prime factorization of 8:
8 = 2 x 2 x 2

Prime factorization of 12:
12 = 2 x 2 x 3

Now, to find the LCM, we take the highest power of each prime factor that appears in either factorization. In this case, the LCM of 8 and 12 is:
LCM(8, 12) = 2^3 x 3 = 24

So, the least common multiple of 8 and 12 is 24.
