Least Common Multiple (LCM) WORKSHEET
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
Least Common Multiple (LCM) WORKSHEET DESCRIPTION
Familiarize students with common multiples, the concept of LCM, and how it is used to problem solve with this worksheet.
In section A, students have three lists of multiples and are asked to circle the numbers that are common multiples of two numbers.
Next up, students will list the first ten multiples of four numbers and use these lists to find the least common multiples of either pairs of numbers or sets of three numbers.
Your learners will take a look at how LCMs are used to solve various problems in section C .
