Questions and Answers

What is the first step in the Factor Tree Method for finding the LCM?

  • Multiplying the two numbers together
  • Drawing a tree diagram for each number (correct)
  • Listing out all prime factors of both numbers
  • Choosing the highest common factor

Why is the Factor Tree Method considered an effective way to find the LCM?

  • It always results in a smaller LCM compared to other methods
  • It guarantees the correct answer without any possibility of errors
  • It is quicker than using the prime factorization method
  • It allows for a visual representation of prime factors (correct)

What role do prime factors play in the Factor Tree Method for finding the LCM?

  • They help in identifying the highest common factor
  • They serve as the building blocks to decompose numbers into simpler components (correct)
  • They are combined to form composite numbers
  • They allow for simplification of fractions
