  • 1. Whole Numbers Multiples What will we learn today? determining if a number is a multiple of a given 1-digit number, listing the first 12 multiples of a given 1-digit number, finding the common multiples of two given 1-digit numbers.

2. We have learnt aboutFACTORS in the last lecture. 3. Its time for us to take it to a new level.Lets try to learnsome new concepts today! Multiples 4. What is a multiple?The result of multiplying a numberby an integer (not a fraction).In the multiplication table, we can see that 3 6 9 12 15 18 21 24 27 30 Therefore, 12 is a multiple of 3, because 3 4 = 12But 7 is NOT a multiple of 3 5. Factors and Multiples Factors and multiples are associated withmultiplication. Factors are what you can multiply to get anumber. Multiples are what you get after multiplying anumber by an integer. factors 3 x 4 = 12multiple 6. List the first 12 multiples of agiven 1-digit numberFor example, 4The first 12 multiples are4 8 12 16 20 24 28 32 36 40 44 48 7. What is the 8th multiple of the digit 4?The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48 8. What is the 8th multiple of the digit 4?The first 12 multiples are 4 8 12 16 20 24 28 32 36 40 44 48 32 is the 8th multiple of the digit 4. 9. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which isless than 30. 10. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30.3 6 9 12 15 18 21 24 27 30Step 1:List down the multiples of 3. 11. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30.3 6 9 12 15 18 21 24 27 308 16 24 32 40 48 56 64 72 80Step 2:List down the multiples of 8. 12. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30.3 6 9 12 15 18 21 24 27 308 16 24 32 40 48 56 64 72 80Step 3:Circle the common multiple(s). 13. Find the common multiples of two given 1-digit numbersFind the common multiple of 3 and 8 which is less than 30.3 6 9 12 15 18 21 24 27 308 16 24 32 40 48 56 64 72 80The common multiple is 24. 14.
