Therefore, GCD of numbers 230, 930, 397, 921 is 1

Given Input Data is 230, 930, 397, 921

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

Prime Factorization of 230 is 2 x 5 x 23

Prime Factorization of 930 is 2 x 3 x 5 x 31

Prime Factorization of 397 is 397

Prime Factorization of 921 is 3 x 307

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(230, 930) = 21390

GCD(230, 930) = ( 230 x 930 ) / 21390

GCD(230, 930) = 213900 / 21390

GCD(230, 930) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 397

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

LCM(10, 397) = 3970

GCD(10, 397) = ( 10 x 397 ) / 3970

GCD(10, 397) = 3970 / 3970

GCD(10, 397) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 921

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

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

GCD(1, 921) = 921 / 921

GCD(1, 921) = 1

GCD of 230, 930, 397, 921 is 1
