Given Input Data is 195, 261, 440, 159

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 261 is 3 x 3 x 29

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

Prime Factorization of 159 is 3 x 53

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, 261) = 16965

GCD(195, 261) = ( 195 x 261 ) / 16965

GCD(195, 261) = 50895 / 16965

GCD(195, 261) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 440

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

LCM(3, 440) = 1320

GCD(3, 440) = ( 3 x 440 ) / 1320

GCD(3, 440) = 1320 / 1320

GCD(3, 440) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 159

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

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

GCD(1, 159) = 159 / 159

GCD(1, 159) = 1

GCD of 195, 261, 440, 159 is 1
