2 2 ARRANGEMENT OF STARS Take 6 stars and arrange them in different ways

3 3 1 Row × 6 Stars/Row = 6 Stars

4 4 3 Rows × 2 Stars per row = 6 stars

5 5 2 Rows × 3 stars per row = 6 stars

6 6 6 Rows × 1 Star/Row = 6 Stars

7 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 8 ARRANGEMENT OF FOOTBALLS Take 8 footballs and arrange them in different ways

9 9 Arrangement of 8 in different ways 1 Row × 8 Balls/Row = 8 Balls

10 10 2 Rows × 4 Balls / Row = 8 Balls

11 11 4 Rows × 2 Balls / Row = 8 Balls

12 12 8 Rows × 1 Ball / Row = 8 Balls

13 13 1, 2, 4 and 8 are exact divisors of 8.

14 14 7 divides 28 exactly and gives Quotient 4 and Remainder ÷ 7 = 4

15 15 4 divides 28 exactly and gives Quotient 7 and Remainder ÷ 4 = 7

16 16 28 divides 28 exactly and gives Quotient 1 and Remainder ÷ 28 = 1

17 17 28 ÷ 1 = ÷ 4 = 7 28 ÷ 7 = 4 28 ÷ 28= FACTORS OF 28

18 18 16 ÷ 1 = ÷ 2 = 8 16 ÷ 4 = 4 16 ÷ 8 = 2 16 ÷ 16 = FACTORS OF 16

19 19 FACTOR A factor of a number is an exact divisor of that number i.e. the factor leaves remainder 0 when it divides the number.

20 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 is the multiple of 2 and 12. So, a number is a multiple of its factors.

21 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 22 FACTORS OF SOME NUMBERS 8 = 1,2,4,8 16 = 1,2,4,8,16 25 = 1,5,25

23 23 4 × 5 = 20 FactorsMultiple

24 24 POINTS TO REMEMBER 1 is a factor of every number. Every factor of a number is an exact divisor of that number. Every factor is less than or equal to the given number. Number of factors of a given number are finite.

25 25 Every multiple of a number is greater than or equal to that number. The number of multiples of a given number is infinite. Every number is a multiple of itself. POINTS TO REMEMBER contd

26 26 FACTOR OR MULTIPLE? For each of numbers in the statements, select either multiple [M] or factor [F] 33334 × 5 = 170 [ FFFF] [ MMMM] [ FFFF] [ MMMM] [ FFFF] [ MMMM] 22225 × 4 = 100 [ FFFF] [ MMMM] [ FFFF] [ MMMM] [ FFFF] [ MMMM] 99990 × 10 = 900 [ FFFF] [ MMMM] [ FFFF] [ MMMM] [ FFFF] [ MMMM] 44445 × 6 = 270 [ FFFF] [ MMMM] [ FFFF] [ MMMM] [ FFFF] [ MMMM]  7 × 30 = 210 [ FFFF] [ MMMM] [ FFFF] [ MMMM] [ FFFF] [ MMMM]

27 27 State whether the following statements are TRUE or FALSE 1. 1 is a factor of every number. F T FT FT 2. The largest factor of any number is the number itself. F T F T F T 3. Number of factors of a given number is infinite. F T FT FT 4.The number of multiples of 5 is 10. F T FT FT 5.The factors of 65 are 1, 5 and 13 only. F T FT FT ( Click ‘F’ for false and ‘T’ for true )

28 28 THANK YOU

29 29 CORRECT

30 30 WRONG
