Therefore, GCD of numbers 640, 184, 81, 599 is 1

Given Input Data is 640, 184, 81, 599

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 184 is 2 x 2 x 2 x 23

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 599 is 599

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, 184) = 14720

GCD(640, 184) = ( 640 x 184 ) / 14720

GCD(640, 184) = 117760 / 14720

GCD(640, 184) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 81

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

LCM(8, 81) = 648

GCD(8, 81) = ( 8 x 81 ) / 648

GCD(8, 81) = 648 / 648

GCD(8, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 599

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

LCM(1, 599) = 599

GCD(1, 599) = ( 1 x 599 ) / 599

GCD(1, 599) = 599 / 599

GCD(1, 599) = 1

GCD of 640, 184, 81, 599 is 1
