Finding the GCF and LCM using Venn Diagrams WORKSHEET
Suitable for Grades: 5th Grade, 6th Grade
CCSS: 5.NF.A.1, 6.NS.B.4
CCSS Description: CCSS Description: Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12.(In general, a/b + c/d = (ad + bc)/bd.)
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).

Finding the GCF and LCM using Venn Diagrams WORKSHEET DESCRIPTION
This worksheet extensively covers finding the greatest common factor and least common multiple of pairs of numbers. Our aim is to equip learners with solid methods that they can replicate for themselves.
Section A consists of six venn diagrams into which students will enter factors of pairs of numbers, before identifying the GCF of each pair.
In section B, learners will list the first 10 multiples of numbers, identify common multiples, and choose the LCM of five pairs of numbers.
Lastly, section C is made up of 15 mixed GCF and LCM questions in order to provide sufficient practice for your students.
