Given Input Data is 912, 640, 578, 197

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

Prime Factorization of 912 is 2 x 2 x 2 x 2 x 3 x 19

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

Prime Factorization of 578 is 2 x 17 x 17

Prime Factorization of 197 is 197

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(912, 640) = 36480

GCD(912, 640) = ( 912 x 640 ) / 36480

GCD(912, 640) = 583680 / 36480

GCD(912, 640) = 16

Step2:

Here we consider the GCD from the above i.e. 16 as first number and the next as 578

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

LCM(16, 578) = 4624

GCD(16, 578) = ( 16 x 578 ) / 4624

GCD(16, 578) = 9248 / 4624

GCD(16, 578) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 197

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

LCM(2, 197) = 394

GCD(2, 197) = ( 2 x 197 ) / 394

GCD(2, 197) = 394 / 394

GCD(2, 197) = 1

GCD of 912, 640, 578, 197 is 1
