Question

The greatest number which will divide 116, 221, 356 leaving the same remainder in each case is

Answer 1

Answer:

Step-by-step explanation:

The answer is 4 and how it is 4 is below,

 

We can represent any integer number in the form of: D*q + r.

Where D is divisor, q is quotient, r is remainder.

so each number can be written accordingly:

43 = D*q1 + r1;

91 = D*q2 + r2;

183 = D*q3 + r3;

r1,r2 & r3 will be same in above three equations according to the question.

D is the value that we want to find out. which should be greatest.

On solving three equations we get:

D*(q2-q1)= (91-43)=48

D*(q3-q2)= (183-91)=92

D*(q3-q1)= (183-43)=140

It is obvious that q3>q2>q1

For the greatest value of D that divide each equation we take th...
