Correct Answer - Option 2 : 21
Given:
Our given number are 366, 513 and 324
Concept used:
The greatest number which divides the three numbers x, y and z and leaving the same remainder in each case then the required number is HCF of (x – y, y – z, z – x)
Calculation:
Our given number are 513, 366 and 324
Now, (513 – 366), (366 – 324), (513 – 324)
⇒ 147, 42, 189
HCF of 147, 42, 189 is 21
∴ The required number is 21
