Given Input Data is 27, 327, 549, 787

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

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 327 is 3 x 109

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 787 is 787

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(27, 327) = 2943

GCD(27, 327) = ( 27 x 327 ) / 2943

GCD(27, 327) = 8829 / 2943

GCD(27, 327) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 549

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

LCM(3, 549) = 549

GCD(3, 549) = ( 3 x 549 ) / 549

GCD(3, 549) = 1647 / 549

GCD(3, 549) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 787

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

LCM(3, 787) = 2361

GCD(3, 787) = ( 3 x 787 ) / 2361

GCD(3, 787) = 2361 / 2361

GCD(3, 787) = 1

GCD of 27, 327, 549, 787 is 1
