Find the greatest number that will divide 47, 95 and 187 so as to leave the same remainder in each case.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4
The greatest number that will divide a, b and c so as to leave the same remainder in each case will be HCF of (a - b), (b - c), (c - a)
so we have to find HCF of (95 - 47), (187 - 95), (187 - 47)
HCF of 48, 92, 140
HCF = 4.
