Given Input Data is 978, 537, 439, 382

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

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 537 is 3 x 179

Prime Factorization of 439 is 439

Prime Factorization of 382 is 2 x 191

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(978, 537) = 175062

GCD(978, 537) = ( 978 x 537 ) / 175062

GCD(978, 537) = 525186 / 175062

GCD(978, 537) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 439

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

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

GCD(3, 439) = 1317 / 1317

GCD(3, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 382

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

LCM(1, 382) = 382

GCD(1, 382) = ( 1 x 382 ) / 382

GCD(1, 382) = 382 / 382

GCD(1, 382) = 1

GCD of 978, 537, 439, 382 is 1
