- 1. FACTORS & MULTIPLES . Powerpoint hosted on www.worldofteaching.com Please visit for 100’s more free powerpoints
- 2. ARRANGEMENT OF STARS Take 6 stars and arrange them in different ways
- 3. 1 Row × 6 Stars/Row = 6 Stars
- 4. 3 Rows × 2 Stars per row = 6 stars
- 5. 2 Rows × 3 stars per row = 6 stars
- 6. 6 Rows × 1 Star/Row = 6 Stars
- 7. As we can see, 6 can be written as product of two numbers in many ways: 6 = 1 × 6 6 = 2 × 3 6 = 3 × 2 6 = 6 × 1 1, 2, 3 and 6 are exact divisors of 6
- 8. ARRANGEMENT OF FOOTBALLS Take 8 footballs and arrange them in different ways
- 9. Arrangement of 8 in different ways 1 Row × 8 Balls/Row = 8 Balls
- 10. 2 Rows × 4 Balls / Row = 8 Balls
- 11. 4 Rows × 2 Balls / Row = 8 Balls
- 12. 8 Rows × 1 Ball / Row = 8 Balls
- 13. 1, 2, 4 and 8 are exact divisors of 8.
- 14. 7 divides 28 exactly and gives Quotient 4 and Remainder 0. 28 ÷ 7 = 4
- 15. 4 divides 28 exactly and gives Quotient 7 and Remainder 0. 28 ÷ 4 = 7
- 16. 28 divides 28 exactly and gives Quotient 1 and Remainder 0. 28 ÷ 28 = 1
- 17. 28 ÷ 1 = 28 28 ÷ 4 = 7 28 ÷ 7 = 4 28 ÷ 28= 1 1 4 7 28 FACTORS OF 28
- 18. 16 ÷ 1 = 16 16 ÷ 2 = 8 16 ÷ 4 = 4 16 ÷ 8 = 2 16 ÷ 16 = 1 1 2 4 8 16 FACTORS OF 16
- 19. FACTOR <ul><li>A factor of a number is an exact divisor of that number i.e. the factor leaves remainder 0 when it divides the number. </li></ul>
- 20. 4 × 5 = 20 4 and 5 are factors of 20. We can also say that 20 is multiple of 4 and 5. In 2 × 12 = 24, 2 and 12 are factors of 24. 24 is the multiple of 2 and 12. So, a number is a multiple of its factors.
- 21. Multiples of 2 = 2,4,6,8,10,12,14,16,18,20,22,24… Multiples of 3 = 3,6,9,12,15,18,21,24,27,30,33,36,… Multiples of 15 = 15,30,4,60,75,90,105,120,135,…… The number of multiples of a given number is infinite.
- 22. FACTORS OF SOME NUMBERS 8 = 1,2,4,8 16 = 1,2,4,8,16 25 = 1,5,25
- 23. 4 × 5 = 20 Factors Multiple
- 24. POINTS TO REMEMBER <ul><li>1 is a factor of every number. </li></ul><ul><li>Every factor of a number is an exact divisor of that number. </li></ul><ul><li>Every factor is less than or equal to the given number. </li></ul><ul><li>Number of factors of a given number are finite. </li></ul>
- 25. <ul><li>Every multiple of a number is greater than or equal to that number. </li></ul><ul><li>The number of multiples of a given number is infinite. </li></ul><ul><li>Every number is a multiple of itself. </li></ul>POINTS TO REMEMBER contd
- 26. THANK YOU
