First method 

Factor of 70 =1,2,5,7,10,14,35,70 

Factor of 105 = 1,3.,5,7,15,21,35,105 

Factor of 175 = 1,5,7,25,35,175 

----------------------------------------

SECOND METHOD 

Factor of 70 = 2x5x7 

Factor of 105 = 3x5x7 

Factor of 175 = 5X5X7 

--------------------------------------- 

Common Factor = 5x7 =35 

H.C.F.of 70,105, 175 is 35 Ans 

THIRD METHOD 

70)105(1 

------70 

------------ 

35)70(2 

----- 70 

---------------- 

35) 175( 7
