Given Input Data is 656, 636, 233, 921

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

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 233 is 233

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(656, 636) = 104304

GCD(656, 636) = ( 656 x 636 ) / 104304

GCD(656, 636) = 417216 / 104304

GCD(656, 636) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 233

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

LCM(4, 233) = 932

GCD(4, 233) = ( 4 x 233 ) / 932

GCD(4, 233) = 932 / 932

GCD(4, 233) = 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 656, 636, 233, 921 is 1
