Therefore, GCD of numbers 86, 430, 126, 391 is 1

Given Input Data is 86, 430, 126, 391

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 430 is 2 x 5 x 43

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

Prime Factorization of 391 is 17 x 23

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(86, 430) = 430

GCD(86, 430) = ( 86 x 430 ) / 430

GCD(86, 430) = 36980 / 430

GCD(86, 430) = 86

Step2:

Here we consider the GCD from the above i.e. 86 as first number and the next as 126

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

LCM(86, 126) = 5418

GCD(86, 126) = ( 86 x 126 ) / 5418

GCD(86, 126) = 10836 / 5418

GCD(86, 126) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 391

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

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

GCD(2, 391) = 782 / 782

GCD(2, 391) = 1

GCD of 86, 430, 126, 391 is 1
