We found the divisors of 681, 606, 307, 621 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 681, 606, 307, 621 is 1.

Therefore, GCD of numbers 681, 606, 307, 621 is 1

Given Input Data is 681, 606, 307, 621

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 307 is 307

Prime Factorization of 621 is 3 x 3 x 3 x 23

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, 606) = 137562

GCD(681, 606) = ( 681 x 606 ) / 137562

GCD(681, 606) = 412686 / 137562

GCD(681, 606) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 307

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

LCM(3, 307) = 921

GCD(3, 307) = ( 3 x 307 ) / 921

GCD(3, 307) = 921 / 921

GCD(3, 307) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

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

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

GCD of 681, 606, 307, 621 is 1
