**Solving LCM Sums**

LCM stands for Lowest Common Multiple. It is the smallest multiple that two or more numbers have in common. When solving LCM sums, you need to find the LCM of the given numbers. Here's a step-by-step guide on how to solve LCM sums:

**Step 1: Understand the Problem**
Read the problem carefully and make sure you understand what you are being asked to find. Identify the numbers for which you need to find the LCM.

**Step 2: Prime Factorization**
Prime factorization is the process of breaking down a number into its prime factors. To find the LCM, you need to express each number as a product of its prime factors.

**Step 3: Identify Common and Uncommon Factors**
Identify the prime factors of each number and group them into common and uncommon factors. Common factors are the ones that appear in all the numbers, while uncommon factors are unique to each number.

**Step 4: Multiply Common Factors**
Multiply all the common factors together. These will be part of the LCM.

**Step 5: Multiply Uncommon Factors**
Take the remaining uncommon factors and multiply them together. These will also be part of the LCM.

**Step 6: Calculate the LCM**
Multiply the product of the common factors by the product of the uncommon factors to get the LCM. This will be the smallest multiple that the given numbers have in common.

**Step 7: Check Your Answer**
To verify your answer, divide the LCM by each of the given numbers. If the LCM is divisible by all the numbers without leaving any remainder, then your answer is correct.

By following these steps, you can easily solve LCM sums. Practice solving different LCM problems to improve your understanding and speed.
