Therefore, GCD of numbers 685, 621, 908 is 1

Given Input Data is 685, 621, 908

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

Prime Factorization of 685 is 5 x 137

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

Prime Factorization of 908 is 2 x 2 x 227

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(685, 621) = 425385

GCD(685, 621) = ( 685 x 621 ) / 425385

GCD(685, 621) = 425385 / 425385

GCD(685, 621) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 908

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

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

GCD(1, 908) = 908 / 908

GCD(1, 908) = 1

GCD of 685, 621, 908 is 1
