Find the greatest number that will divide 43, 91 and 183 so as to leave the same remainder in each case.
Answer: Option
Explanation:
Required number = H.C.F. of (91 - 43), (183 - 91) and (183 - 43)
= H.C.F. of 48, 92 and 140 = 4.

@Parthiban.
If there is large numbers then it is reliable method to divide and then finding highest common factor?

Hey friends I will say one example of HCF.
Eg..72and 126...then,
Using Division method First find H.C.F. of 72 and 126.
H.C.F. of 72 and 126 = 18.
Similarly calculate H.C.F. of 18 and 270 as 18.
Hence H.C.F. of the given three numbers = 18.
Eg..72and 126...then,

H.C.F. of 72 and 126 = 18.
Similarly calculate H.C.F. of 18 and 270 as 18.
Hence H.C.F. of the given three numbers = 18.

43%4 = 3.
91%4 = 3.
183%4 = 3.
That's why answer is 4.
91%4 = 3.
183%4 = 3.
That's why answer is 4.
