Given Input Data is 679, 434, 620, 862

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

Prime Factorization of 679 is 7 x 97

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 862 is 2 x 431

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(679, 434) = 42098

GCD(679, 434) = ( 679 x 434 ) / 42098

GCD(679, 434) = 294686 / 42098

GCD(679, 434) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 620

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

LCM(7, 620) = 4340

GCD(7, 620) = ( 7 x 620 ) / 4340

GCD(7, 620) = 4340 / 4340

GCD(7, 620) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 862

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

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

GCD(1, 862) = 862 / 862

GCD(1, 862) = 1

GCD of 679, 434, 620, 862 is 1
