Given Input Data is 195, 640, 985, 104

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

Prime Factorization of 195 is 3 x 5 x 13

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 104 is 2 x 2 x 2 x 13

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(195, 640) = 24960

GCD(195, 640) = ( 195 x 640 ) / 24960

GCD(195, 640) = 124800 / 24960

GCD(195, 640) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 985

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

LCM(5, 985) = 985

GCD(5, 985) = ( 5 x 985 ) / 985

GCD(5, 985) = 4925 / 985

GCD(5, 985) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 104

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

LCM(5, 104) = 520

GCD(5, 104) = ( 5 x 104 ) / 520

GCD(5, 104) = 520 / 520

GCD(5, 104) = 1

GCD of 195, 640, 985, 104 is 1
