I am having a lot of trouble with LCM (Least Common Multiple) and GCF (Greatest Common Factor) and is the only reason why I'm getting bad grades in Math. The problem is that I can't find the least or greatest factor/multiple. I can find the a common factor and multiple but it's not the greatest or the least. What can I do and can you help me? Thanks

Sure, I can definitely help you with finding the LCM (Least Common Multiple) and GCF (Greatest Common Factor). Let's start with the explanation.

The LCM is the smallest multiple that two or more numbers have in common, while the GCF is the largest factor that two or more numbers have in common. These concepts are important in various mathematical operations, such as simplifying fractions, comparing fractions, adding and subtracting fractions, and solving equations.

To find the LCM and GCF of two or more numbers, you can follow these steps:

1. Start by listing the prime factors of each number.

2. Identify the common prime factors between the numbers.

3. For finding the LCM:

   - Multiply all the common prime factors and the unique prime factors from all the numbers.

   - This will give you the LCM of the given numbers.

4. For finding the GCF:

   - Multiply only the common prime factors between the numbers.

   - This will give you the GCF of the given numbers.

Now, let's move on to your specific question. Could you please provide me with the numbers for which you want to find the LCM and GCF?
