Given Input Data is 774, 122, 86, 430

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

Prime Factorization of 774 is 2 x 3 x 3 x 43

Prime Factorization of 122 is 2 x 61

Prime Factorization of 86 is 2 x 43

Prime Factorization of 430 is 2 x 5 x 43

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(774, 122) = 47214

GCD(774, 122) = ( 774 x 122 ) / 47214

GCD(774, 122) = 94428 / 47214

GCD(774, 122) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 86

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

LCM(2, 86) = 86

GCD(2, 86) = ( 2 x 86 ) / 86

GCD(2, 86) = 172 / 86

GCD(2, 86) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 430

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

LCM(2, 430) = 430

GCD(2, 430) = ( 2 x 430 ) / 430

GCD(2, 430) = 860 / 430

GCD(2, 430) = 2

GCD of 774, 122, 86, 430 is 2
