Find HCF of the following pair of numbers by Euclidâ€™s game.**

**i)
25 and 35**

**ii)
36 and 12 **

**iii)
15 and 29**

Answer:

**i) 25 and 35**

__H.C.F. of 25 and 35 __

25 = 5 Ã— 5

35 = 5 Ã— 7

**H.C.F. of 25 and 35
= 5**

__H.C.F. of (25, 35 âˆ’ 25)__

25 = 5 Ã— 5

10 = 2 Ã— 5

**H.C.F. of (25, 10)
= 5**

**âˆ´**** H.C.F of 25 and 35 = H.C.F of (25, 35 âˆ’ 25)**

**ii) 36 and 12**

__H.C.F. of 36 and 12 __

36 = 2 Ã— 2 Ã— 3 Ã— 3

12 = 2 Ã— 2 Ã— 3

__H.C.F. of (12, 36 âˆ’ 12)__

12 = 2 Ã— 2 Ã— 3

24 = 2 Ã— 2 Ã— 2 Ã— 3

**H.C.F. of (12, 24) = 2 Ã— 2 Ã— 3 = 12â€ƒ**

H.C.F of 36 and 12 = 2 Ã— 2
Ã— 3 = 12

âˆ´ H.C.F of 36 and 12 =
H.C.F of (12, 36 âˆ’ 12)

**iii) 15 and 29**

__H.C.F. of 15 and 29 __

15 = 3 Ã— 5

29 = 1 Ã— 29

**H.C.F. of 15 and 29
= 1**

__H.C.F. of (15, 29 â€“ 15)__

15 = 3 Ã— 5

14 = 2 Ã— 7

**H.C.F. of (15, 14)
= 1**

**âˆ´**** H.C.F of 15 and 29 =
H.C.F of (15, 29 âˆ’ 15)**

** **

**6.
Find HCF of 48 and 28. Also find the HCF of 48 and the number obtained by finding
their difference.**

Answer:

__H.C.F. of 48 and 28 __

48 = 2 Ã— 2 Ã— 2 Ã— 2 Ã— 3

28 = 2 Ã— 2 Ã— 7

**H.C.F. of 48 and 28 = 2 Ã— 2 = 4**

__H.C.F. of (48, 48 âˆ’ 28)__

48 = 2 Ã— 2 Ã— 2 Ã— 2 Ã— 3

20 = 2 Ã— 2 Ã— 5

**H.C.F. of (48, 20) = 2 Ã— 2 = 4**
