Given Input Data is 97, 485, 642, 139

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

Prime Factorization of 97 is 97

Prime Factorization of 485 is 5 x 97

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 139 is 139

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(97, 485) = 485

GCD(97, 485) = ( 97 x 485 ) / 485

GCD(97, 485) = 47045 / 485

GCD(97, 485) = 97

Step2:

Here we consider the GCD from the above i.e. 97 as first number and the next as 642

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

LCM(97, 642) = 62274

GCD(97, 642) = ( 97 x 642 ) / 62274

GCD(97, 642) = 62274 / 62274

GCD(97, 642) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 139

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

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

GCD(1, 139) = 139 / 139

GCD(1, 139) = 1

GCD of 97, 485, 642, 139 is 1
