Given Input Data is 485, 921, 828, 388

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

Prime Factorization of 485 is 5 x 97

Prime Factorization of 921 is 3 x 307

Prime Factorization of 828 is 2 x 2 x 3 x 3 x 23

Prime Factorization of 388 is 2 x 2 x 97

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(485, 921) = 446685

GCD(485, 921) = ( 485 x 921 ) / 446685

GCD(485, 921) = 446685 / 446685

GCD(485, 921) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 828

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

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

GCD(1, 828) = 828 / 828

GCD(1, 828) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 388

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

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

GCD(1, 388) = 388 / 388

GCD(1, 388) = 1

GCD of 485, 921, 828, 388 is 1
