Worksheet Description

This worksheet is a mathematical exercise focused on finding the Least Common Multiple (LCM) for pairs of numbers. It consists of six problems, with the first one completed as an example, showing the prime factorization method to calculate the LCM. The example illustrates how to divide the numbers by common prime factors and then multiply these factors together to find the LCM, in this case, of 20 and 30. The remaining problems provide space for students to work out the LCM in a similar manner, encouraging independent practice of the demonstrated method.

The worksheet is teaching students to understand and apply the concept of the Least Common Multiple through the prime factorization method. It encourages the development of factorization skills and the understanding of how to build the LCM from these factors. By completing the exercise, students learn to recognize and use prime numbers as building blocks for finding multiples that two or more numbers share. This skill is essential for solving problems involving fractions, least common denominators, and is a foundational concept in number theory.
