Given Input Data is 978, 526, 390, 711

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

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 526 is 2 x 263

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 711 is 3 x 3 x 79

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(978, 526) = 257214

GCD(978, 526) = ( 978 x 526 ) / 257214

GCD(978, 526) = 514428 / 257214

GCD(978, 526) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 390

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

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

GCD(2, 390) = 780 / 390

GCD(2, 390) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 711

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

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

GCD(2, 711) = 1422 / 1422

GCD(2, 711) = 1

GCD of 978, 526, 390, 711 is 1
