Therefore, GCD of numbers 981, 363, 271, 247 is 1

Given Input Data is 981, 363, 271, 247

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 363 is 3 x 11 x 11

Prime Factorization of 271 is 271

Prime Factorization of 247 is 13 x 19

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(981, 363) = 118701

GCD(981, 363) = ( 981 x 363 ) / 118701

GCD(981, 363) = 356103 / 118701

GCD(981, 363) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 271

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 271) = 813

GCD(3, 271) = ( 3 x 271 ) / 813

GCD(3, 271) = 813 / 813

GCD(3, 271) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 247

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

GCD(1, 247) = 247 / 247

GCD(1, 247) = 1

GCD of 981, 363, 271, 247 is 1
