LCM (Lowest Common Multiple) WORKSHEET
Suitable for Grades: 4th Grade
CCSS: 4.OA.A.2, 4.OA.B.4
CCSS Description: Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.

LCM (Lowest Common Multiple) WORKSHEET DESCRIPTION
Familiarise 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 lowest 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 .
