Given Input Data is 629, 481, 821

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

Prime Factorization of 629 is 17 x 37

Prime Factorization of 481 is 13 x 37

Prime Factorization of 821 is 821

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(629, 481) = 8177

GCD(629, 481) = ( 629 x 481 ) / 8177

GCD(629, 481) = 302549 / 8177

GCD(629, 481) = 37

Step2:

Here we consider the GCD from the above i.e. 37 as first number and the next as 821

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

LCM(37, 821) = 30377

GCD(37, 821) = ( 37 x 821 ) / 30377

GCD(37, 821) = 30377 / 30377

GCD(37, 821) = 1

GCD of 629, 481, 821 is 1
