Given Input Data is 237, 921, 857, 355

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

Prime Factorization of 237 is 3 x 79

Prime Factorization of 921 is 3 x 307

Prime Factorization of 857 is 857

Prime Factorization of 355 is 5 x 71

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(237, 921) = 72759

GCD(237, 921) = ( 237 x 921 ) / 72759

GCD(237, 921) = 218277 / 72759

GCD(237, 921) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 857

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

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

GCD(3, 857) = 2571 / 2571

GCD(3, 857) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 355

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

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

GCD(1, 355) = 355 / 355

GCD(1, 355) = 1

GCD of 237, 921, 857, 355 is 1
