So the Greatest Common Divisior 231, 126, 139, 605 is 1.

Therefore, GCD of numbers 231, 126, 139, 605 is 1

Given Input Data is 231, 126, 139, 605

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

Prime Factorization of 231 is 3 x 7 x 11

Prime Factorization of 126 is 2 x 3 x 3 x 7

Prime Factorization of 139 is 139

Prime Factorization of 605 is 5 x 11 x 11

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(231, 126) = 1386

GCD(231, 126) = ( 231 x 126 ) / 1386

GCD(231, 126) = 29106 / 1386

GCD(231, 126) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 139

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

LCM(21, 139) = 2919

GCD(21, 139) = ( 21 x 139 ) / 2919

GCD(21, 139) = 2919 / 2919

GCD(21, 139) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

GCD of 231, 126, 139, 605 is 1
