Given Input Data is 777, 854, 668, 249

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 854 is 2 x 7 x 61

Prime Factorization of 668 is 2 x 2 x 167

Prime Factorization of 249 is 3 x 83

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, 854) = 94794

GCD(777, 854) = ( 777 x 854 ) / 94794

GCD(777, 854) = 663558 / 94794

GCD(777, 854) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 668

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

LCM(7, 668) = 4676

GCD(7, 668) = ( 7 x 668 ) / 4676

GCD(7, 668) = 4676 / 4676

GCD(7, 668) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 249

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

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

GCD(1, 249) = 249 / 249

GCD(1, 249) = 1

GCD of 777, 854, 668, 249 is 1
