Therefore, GCD of numbers 777, 687, 635, 339 is 1

Given Input Data is 777, 687, 635, 339

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

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 687 is 3 x 229

Prime Factorization of 635 is 5 x 127

Prime Factorization of 339 is 3 x 113

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(777, 687) = 177933

GCD(777, 687) = ( 777 x 687 ) / 177933

GCD(777, 687) = 533799 / 177933

GCD(777, 687) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 635

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

LCM(3, 635) = 1905

GCD(3, 635) = ( 3 x 635 ) / 1905

GCD(3, 635) = 1905 / 1905

GCD(3, 635) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 339

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

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

GCD(1, 339) = 339 / 339

GCD(1, 339) = 1

GCD of 777, 687, 635, 339 is 1
