Prime Factors

Worksheet Description

This worksheet is about calculating the Least Common Multiple (LCM) of a pair of numbers using prime factorization. Each problem set presents two numbers for which students are to find the LCM. The first problem is solved as an example, showing the prime factors of the numbers 20 and 8 and how these factors are used to calculate the LCM. There are eight problems in total, and students are expected to apply the demonstrated method to solve the remaining problems.

The worksheet teaches the method of using prime factorization to find the LCM, which is a more systematic and reliable way compared to listing multiples. By breaking down each number into its prime factors, students can easily identify the common factors and calculate the LCM by multiplying these factors together. This approach enhances students’ understanding of prime numbers and their role in number theory. The worksheet also reinforces the importance of the LCM in various mathematical applications, such as finding common denominators in fraction operations.
