Given Input Data is 855, 115, 407, 266

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

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 115 is 5 x 23

Prime Factorization of 407 is 11 x 37

Prime Factorization of 266 is 2 x 7 x 19

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(855, 115) = 19665

GCD(855, 115) = ( 855 x 115 ) / 19665

GCD(855, 115) = 98325 / 19665

GCD(855, 115) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 407

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

LCM(5, 407) = 2035

GCD(5, 407) = ( 5 x 407 ) / 2035

GCD(5, 407) = 2035 / 2035

GCD(5, 407) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 266

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

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

GCD(1, 266) = 266 / 266

GCD(1, 266) = 1

GCD of 855, 115, 407, 266 is 1
