Given Input Data is 668, 164, 859, 662

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

Prime Factorization of 668 is 2 x 2 x 167

Prime Factorization of 164 is 2 x 2 x 41

Prime Factorization of 859 is 859

Prime Factorization of 662 is 2 x 331

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(668, 164) = 27388

GCD(668, 164) = ( 668 x 164 ) / 27388

GCD(668, 164) = 109552 / 27388

GCD(668, 164) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 859

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

LCM(4, 859) = 3436

GCD(4, 859) = ( 4 x 859 ) / 3436

GCD(4, 859) = 3436 / 3436

GCD(4, 859) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 662

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

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

GCD(1, 662) = 662 / 662

GCD(1, 662) = 1

GCD of 668, 164, 859, 662 is 1
