Given Input Data is 399, 273, 776, 787

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 273 is 3 x 7 x 13

Prime Factorization of 776 is 2 x 2 x 2 x 97

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(399, 273) = 5187

GCD(399, 273) = ( 399 x 273 ) / 5187

GCD(399, 273) = 108927 / 5187

GCD(399, 273) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 776

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

LCM(21, 776) = 16296

GCD(21, 776) = ( 21 x 776 ) / 16296

GCD(21, 776) = 16296 / 16296

GCD(21, 776) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 399, 273, 776, 787 is 1
