Given Input Data is 640, 284, 328, 769

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 284 is 2 x 2 x 71

Prime Factorization of 328 is 2 x 2 x 2 x 41

Prime Factorization of 769 is 769

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(640, 284) = 45440

GCD(640, 284) = ( 640 x 284 ) / 45440

GCD(640, 284) = 181760 / 45440

GCD(640, 284) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 328

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

LCM(4, 328) = 328

GCD(4, 328) = ( 4 x 328 ) / 328

GCD(4, 328) = 1312 / 328

GCD(4, 328) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 769

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

LCM(4, 769) = 3076

GCD(4, 769) = ( 4 x 769 ) / 3076

GCD(4, 769) = 3076 / 3076

GCD(4, 769) = 1

GCD of 640, 284, 328, 769 is 1
