Given Input Data is 543, 432, 158, 679

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

Prime Factorization of 543 is 3 x 181

Prime Factorization of 432 is 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 158 is 2 x 79

Prime Factorization of 679 is 7 x 97

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(543, 432) = 78192

GCD(543, 432) = ( 543 x 432 ) / 78192

GCD(543, 432) = 234576 / 78192

GCD(543, 432) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 158

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

LCM(3, 158) = 474

GCD(3, 158) = ( 3 x 158 ) / 474

GCD(3, 158) = 474 / 474

GCD(3, 158) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 679

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

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

GCD(1, 679) = 679 / 679

GCD(1, 679) = 1

GCD of 543, 432, 158, 679 is 1
