Given Input Data is 681, 660, 652, 662

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 652 is 2 x 2 x 163

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(681, 660) = 149820

GCD(681, 660) = ( 681 x 660 ) / 149820

GCD(681, 660) = 449460 / 149820

GCD(681, 660) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 652

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

LCM(3, 652) = 1956

GCD(3, 652) = ( 3 x 652 ) / 1956

GCD(3, 652) = 1956 / 1956

GCD(3, 652) = 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 681, 660, 652, 662 is 1
