Given Input Data is 273, 549, 638

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

Prime Factorization of 273 is 3 x 7 x 13

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 638 is 2 x 11 x 29

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(273, 549) = 49959

GCD(273, 549) = ( 273 x 549 ) / 49959

GCD(273, 549) = 149877 / 49959

GCD(273, 549) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 638

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

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

GCD(3, 638) = 1914 / 1914

GCD(3, 638) = 1

GCD of 273, 549, 638 is 1
