This includes blank sheets to use for other numbers. These are activity sheets for students to use to fill out to make it easier to show the GCF and LCM and easier to remember the difference.
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).
