Given numbers are 188 and 230
Euclid's game:
HCF of 188 and 230 \(\Rightarrow\) (188, 230)
\(\Rightarrow\) (188, 230 - 188)
\(\Rightarrow\) (188,42) = 188 - 42 = 146
\(\Rightarrow\) (146, 42) = 146 - 42 = 104
\(\Rightarrow\)(104, 42) = 104 - 42 = 62
\(\Rightarrow\) (62, 42) = 62 - 42 = 20
\(\Rightarrow\) (20, 42) = 42 - 20 = 22
\(\Rightarrow\) (22, 20) = (22 - 20) = 2
\(\Rightarrow\) (2, 20) = 20 - 2 = 18
\(\Rightarrow\)(18, 2) = 18 - 2 = 16
\(\Rightarrow\)(16, 2) = 16 - 2 = 14
\(\Rightarrow\)(14, 2)= 14 - 2 = 12
\(\Rightarrow\)(12, 2) = 12 - 2 = 10
\(\Rightarrow\)(10, 2) = 10 - 2 = 8
\(\Rightarrow\)(8, 2) \(\Rightarrow\) 8 - 2 = 6
\(\Rightarrow\) (6, 2) \(\Rightarrow\)6 - 2 = 4
\(\Rightarrow\) (4, 2) \(\Rightarrow\) 4 - 2 = 2
\(\Rightarrow\) (2, 2)
\(\therefore\) HCF of 188 and 430 is 2.

i) Prime numbers = 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31
Composite numbers = 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 21, 22, 24, 25, 26, 27, 28, 30
ii) Odd numbers = 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31
Even numbers = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28
iii) Multiplies of 6 = 6, 12, 18, 24, 30,
Multiplies of 4 = 4, 8, 12, 16, 20, 24, 28
Common multiples = 12, 24
LCM = 12
iv) Monday falls on = 7, 14, 21, 28

10.

Let us take a number = 6
Multiply it by 9 = 9 \(\times\) 6 = 54
Add the digits together : 5 + 4 = 9
Subtract 3 from the answer : 9 – 3 = 6
Multiply the number by itself : 6 \(\times\) 6 = 36
Try for number other than 6.

Given numbers are 48 and 28
HCF of 48 and 28
\(\Rightarrow\) (48, 48 - 28)
48 \(\rightarrow\) 2 \(\times\) 2 \(\times\) 2 \(\times\) 2 \(\times\) 3
20 \(\rightarrow\) 2 \(\times\) 2 \(\times\) 5
HCF = 2 \(\times\) 2 = 4
Also find : HCF of 48 and 4
48 \(\rightarrow\) 2 \(\times\) 2 \(\times\) 2 \(\times\) 2 \(\times\) 3
4 \(\rightarrow\) 2 \(\times\) 2
HCF=2 \(\times\) 2 = 4
Difference = 4 - 4 = 0 [same HCF]

16.

(i) By Euclid's game
Given numbers = 25 and 35
HCF\(\Rightarrow\)(25, 35) = HCF(25, 35 - 25)
= (25, 10)
= (25 - 10, 10) = (15, 10)
= (5, 10)
= (5, 10 - 5)
= (5, 5)
(ii) By Euclid's game
Given numbers = 36 and 12
HCF of 36 and and 12 \(\Rightarrow\)(36, 12)
\(\Rightarrow\) (36 -12, 12)
\(\Rightarrow\)(24, 12)
\(\Rightarrow\)(24 - 12, 12)
\(\Rightarrow\)(12, 12)
\(\therefore\) HCF = 12.
(iii)
Given numbers are 15 and 29
By Euclid's game:
HCF of 15 and 29 is
\(\Rightarrow\)(15, 29)
\(\Rightarrow\)(15, 29 - 15)
\(\Rightarrow\)(15, 14)
\(\Rightarrow\)(15 - 14, 14)
\(\Rightarrow\)(1, 14)\(\Rightarrow\) (1, 14 - 1) \(\Rightarrow\)(1, 13)
\(\Rightarrow\)(1, 13 -1) \(\Rightarrow\)(1, 12) \(\Rightarrow\)(1, 12 -1), (1, 11) (1, 1)
\(\therefore\) HCF = 1
