Question 4 : Find the largest number which divides 64, 136 and 238 to leave the same remainder in each case. Solution : To find the required number, we need to find the HCF of (136-64), (238-136) and (238-64), i.e., HCF (72, 102, 174). 72 = 23 x 32 102 = 2 x 3 ... 3 x 29 Therefore, HCF (72, 102, 174) = 2 x 3 = 6 hence, 6 is the required number. why we find hcf of difference between pairs of number
