Given Input Data is 209, 266, 93, 389

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

Prime Factorization of 209 is 11 x 19

Prime Factorization of 266 is 2 x 7 x 19

Prime Factorization of 93 is 3 x 31

Prime Factorization of 389 is 389

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(209, 266) = 2926

GCD(209, 266) = ( 209 x 266 ) / 2926

GCD(209, 266) = 55594 / 2926

GCD(209, 266) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 93

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

LCM(19, 93) = 1767

GCD(19, 93) = ( 19 x 93 ) / 1767

GCD(19, 93) = 1767 / 1767

GCD(19, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 389

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

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

GCD(1, 389) = 389 / 389

GCD(1, 389) = 1

GCD of 209, 266, 93, 389 is 1
