Understanding LCM through Factor Trees

The video tutorial explains how to find the lowest common multiple (LCM) of 12 and 24 using factor trees. It begins with an introduction to the concept of LCM, followed by a demonstration of creating factor trees to identify prime factors. The tutorial then shows how to organize these prime factors in a chart for clarity. Finally, it explains the process of calculating the LCM by multiplying the necessary factors. The video concludes with a reminder about the importance of kindness.

What is the purpose of finding the Lowest Common Multiple (LCM)?

• To find the smallest number that is a multiple of two or more numbers.

• To find the sum of two numbers.

• To find the largest number that divides two or more numbers.

• To find the difference between two numbers.

What is the first step in creating a factor tree for a number?

• Circle the number.

• Break the number into two factors.

• Multiply the number by 2.

• Divide the number by 3.

Which of the following is a prime factor of 12?

• 8

• 2

• 6

• 4

What is the benefit of using a chart to organize prime factors?

• It helps in organizing and visualizing the factors easily.

• It increases the number of steps required.

• It eliminates the need for calculations.

• It makes the process more complicated.

How many times should a prime factor be written in the chart if it appears twice in a column?

• Not at all

• Thrice

• Once

• Twice

What is the next step after organizing the prime factors in the chart?

• Divide the numbers by 2.

• Add all the numbers together.

• Multiply the numbers together.

• Subtract the numbers.

What is the LCM of 12 and 24?

• 48

• 36

• 24

• 12

What is the result of multiplying 2, 2, 3, and 2 together?

• 18

• 36

What is the final message conveyed in the video?

• Success is the key to happiness.

• Never trust anyone.

• Kindness multiplies kindness.
