Therefore, GCD of numbers 195, 855, 571, 649 is 1

Given Input Data is 195, 855, 571, 649

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 855 is 3 x 3 x 5 x 19

Prime Factorization of 571 is 571

Prime Factorization of 649 is 11 x 59

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, 855) = 11115

GCD(195, 855) = ( 195 x 855 ) / 11115

GCD(195, 855) = 166725 / 11115

GCD(195, 855) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 571

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

LCM(15, 571) = 8565

GCD(15, 571) = ( 15 x 571 ) / 8565

GCD(15, 571) = 8565 / 8565

GCD(15, 571) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 649

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

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

GCD(1, 649) = 649 / 649

GCD(1, 649) = 1

GCD of 195, 855, 571, 649 is 1
