27 = 3*3*3

63=3*3*7

HCF = 9

2) 36,84

36 = 2*2*3*3

84+2*2*3*7

HCF = 12

3) 34,102

34= 2*17

102=2*3*17

HCF = 34

4) 70,105,175

70=2*5*7

105=3*5*7

175=5*5*7

HCF = 35

5) 91,112,49

91=7*13

112=2*2*2*2*7

49=7*7

HCF =7

6) 18,54,81

18 = 2*3*3

54 = 2*3*3*3

81 = 3*3*3*3

HCF = 9

7) 12,45,75

12=2*2*3

45=3*3*5

75=3*5*5

HCF=3
