Conclusion
Common Misconceptions
The Greatest Common Factor (GCF) and Least Common Multiple (LCM) are two related but distinct math concepts. While the GCF is the largest number that divides both numbers without leaving a remainder, the LCM is the smallest number that is a multiple of both numbers. To illustrate this, let's consider the example of 9 and 27. The GCF is 9, while the LCM is 27.
Myth: The GCF of two numbers is always a prime number.
- Listing the factors of each number and identifying the greatest common factor
- Using the Euclidean algorithm to find the GCF
Finding the GCF of three or more numbers involves finding the GCF of two numbers first, and then finding the GCF of the result and the third number. For example, let's find the GCF of 9, 27, and 36. First, we find the GCF of 9 and 27, which is 9. Then, we find the GCF of 9 and 36, which is 9.
