Venn Diagram Method for HCF and LCM
This video shows how to use prime factors in a Venn Diagram to find the greatest common factor or the lowest common multiple of a pair of composite numbers. Finding LCM of two numbers using the Venn diagram. More at www.jbsedweb.weebly.com A Venn diagram showing the least common multiples of 2, 3, 4, 5 and 7 (and of their combinations, like 6 and 8). For example, a card game which requires its cards to be divided equally among up to 5 players requires at least 60 cards, the number at the intersection of the 2, 3, 4, and 5 sets, but not the 7 set. The LCM is found by multiplying all of the numbers in the Venn diagram together. As there are four 2s and two 5s: LCM = 2 × 2 × 2 × 2 × 5 × 5 = 400 The HCF is found by multiplying together.

Finding the. Place these prime factors in a Venn Diagram. The union of the two sets represents the lowest common multiple. This can be written as for example) 9 ∪ 12, or 9 union 12. The LCM (multiply each number on the Venn Diagram) = 2 x 2 x 3 x 3 = 36. The lowest common multiple of 12 and 30 is equal to the product of all the factors viewed in the Venn diagram . The lowest common multiple to be 2 × 2 × 3 × 5 = 60. How to calculate the lowest common multiple In order to calculate the lowest common multiple for two or more numbers:

Variation theory questions Prime factor puzzle HCF and LCM questions OLD VERSION: Tutorial on expressing numbers as products of their prime factors. Moves onto calculating highest common factors and lowest common multiples using prime factors and Venn diagrams. Fully differentiated with extension activity. HCF and LCM RAG using a Venn diagram for LCM and GCF
Once they have found the prime factors of each number help them fill in the Venn diagram. Explain that the number(s) that appear in the center of the Venn diagram represent the GCF. To find the LCM they need to multiply all the numbers in the Venn diagram. Duration. Usually takes two days of class time (42-minute class periods). Materials. intersection of all three sets. From the Venn diagram, it is easy to see that: GCF (8085, 1575, 990) = 3 • 5 = 15. The least common multiple is the product of all the primes in the union of the three sets; that is, LCM (8085, 1575, 990) = 7 • 7 • 5 • 11 • 3 • 5 • 3 • 2 = 242550. Furthermore, this Venn diagram also allows us to.
