General Instructions: 1. 2. 3. 4. 5. 6. 7. 8. Watch the video(factors and multiples) in the upcoming slide. Keep a notebook and pencil to write down any questions and notes. Start the lesson by reading and listening to the voiceover inserted on each slide. Watch the next video slide 7 (common multiples). Read and listen to the given Explanation. Answer the concept check.

Prior knowledge: Watch the Video https: //www. youtube. com/watch? v=cg 0 Dyz Cuc. M 4 Factors A number multiplied by another number to find a product (to find a multiple) � Factor of a number is smaller of equal to the number. � Each number has a definite number of factors � Multiples The product found by multiplying one number by another number. � Multiple of a number is equal or bigger than the number. � Any number is a multiple of all of its factors. � Any number has infinite numbers of multiples. � So, can you find out what is the relation between factors and multiples?

Explanation: let’s have an example to clarify the relation between factors and multiples Factors of 6 � 1 X 6=6 Multiples of 6 1 X 6=6 2 X 6 = 12 � 1 X 3=6 , 2, 3 , 6 3 X 6 = 18 4 X 6 = 24 6, 12 , 18 , 24 , ……………. . So, now we can understand that the relation between factors and multiples is an opposite relation.

The number Tree: Roots are the factors stem is the number itself leaves are the multiples 24 36 48 12 12 1 2 3 4 6 12

Think, and state whether the given sentence is true or false: Every whole number is a multiple of 1 True 2. Every whole number is a factor of 1 False 3. Number 45 is a multiple of 9. True 4. Number 35 is a factor of 7. False 1.

Now, we understand the meaning of multiple, let’s watch this video to learn how to find the common multiples. https: //www. youtube. com/watch? v=Z 6 Lks. V 08 q. U Common Multiples: A number that is a multiple Of two or more numbers.

How to list common multiples of 3 and 5: List the multiples of 3. 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30. 2. List the multiples of 5. 5: 5, 10, 15, 20 , 25, 30. 3. Circle the common multiples. The common multiples are: 15 and 30 The least common multiple (LCM) is 15 1.
