2. 2. 22ARRANGEMENT OF STARSTake 6 stars and arrangethem in differentways
3. 3. 331 Row × 6 Stars/Row = 6 Stars
4. 4. 443 Rows × 2 Stars per row = 6 stars
5. 5. 5522 RowsRows ×× 33 stars per row =stars per row = 66 starsstars
6. 6. 666 Rows × 1 Star/Row= 6 Stars
7. 7. 77As we can see, 6 can be written asproduct of two numbers in manyways: 6 = 1 × 66 = 2 × 36 = 3 × 26 = 6 × 11, 2, 3 and 6 are exact divisors of 6
8. 8. 8ARRANGEMENT OF FOOTBALLSTake 8 footballs and arrangethem in differentways
9. 9. 99Arrangement of 8 indifferent ways1 Row × 8 Balls/Row = 8 Balls
10. 10. 10102 Rows × 4 Balls / Row = 8 Balls
11. 11. 11114 Rows ×2 Balls / Row =8 Balls
12. 12. 12128 Rows × 1 Ball / Row =8 Balls
13. 13. 13131, 2, 4 and 8 areexact divisors of 8.
14. 14. 147 divides 28 exactly andgives Quotient 4 andRemainder 0.28 ÷ 7 = 4
15. 15. 154 divides 28 exactly andgives Quotient 7 andRemainder 0.28 ÷ 4 = 7
16. 16. 1628 divides 28 exactly andgives Quotient 1 andRemainder 0.28 ÷ 28 = 1
17. 17. 1728 ÷ 1 = 2828 ÷ 4 = 728 ÷ 7 = 428 ÷ 28= 114728FACTORS OF 28
18. 18. 1816 ÷ 1 = 1616 ÷ 2 = 816 ÷ 4 = 416 ÷ 8 = 216 ÷ 16 = 112481FACTORS OF 16
19. 19. 19FACTORA factor of a number is an exactdivisor of that number i.e. the factorleaves remainder 0 when it dividesthe number.
20. 20. 204 × 5 = 204 and 5 are factors of 20. We canalso say that 20 is multiple of 4 and5.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 itsfactors.
21. 21. 21Multiples 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 ofa given number is infinite.

24. 24. 24POINTS TO REMEMBER• 1 is a factor of every number.• Every factor of a number is an exactdivisor of that number.• Every factor is less than or equal to thegiven number.• Number of factors of a given number arefinite.
25. 25. 25• Every multiple of a number is greaterthan or equal to that number.• The number of multiples of a givennumber is infinite.• Every number is a multiple of itself.POINTS TO REMEMBERcontd
