Answer is below.
The LCM also known as the "Least Common Multiple" is when you list prime factors, then multiply them.
The first step you would do is to list the factors for each number.
Factors of 8 - 2 × 2 × 2.
Factors of 12 - 2 × 2 × 3.
3 has no factors besides 1 and 3.
After when you list your factors, you'll multiply them.
The LCM is the result of multiplying all prime factors the greatest number of times they occur in either number.
Step 1: Multiply 2 by 2.
2 × 2 = 4
Step 2: Multiply 4 by 2.
4 × 2 = 8
Step 3: Multiply 8 by 3.
8 × 3 = 24
