Given Input Data is 681, 138, 445

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 138 is 2 x 3 x 23

Prime Factorization of 445 is 5 x 89

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, 138) = 31326

GCD(681, 138) = ( 681 x 138 ) / 31326

GCD(681, 138) = 93978 / 31326

GCD(681, 138) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 445

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

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

GCD(3, 445) = 1335 / 1335

GCD(3, 445) = 1

GCD of 681, 138, 445 is 1
