LCM and GCF worksheets

LCM Worksheets are provided below for practice and thus help in better understanding. Math problems involving pairing or grouping can be solved using LCM. LCM is used for optimizing the pairs or groups. LCM, also known as Least Common multiple or Lowest common multiple, is the smallest or the least positive integer that is divisible by a given set of numbers. You can refer to LCM for a better understanding.

GCF Worksheets are provided below for easy understanding and more practice. Math problems involving fractions use GCF to reduce/Simplify the fraction problems. GCF stands for Greatest Common Factor, also known as HCF as in Highest Common Factor, for a given set of numbers is the common factor that is the highest. Refer to GCF for the details.
