Given Input Data is 777, 245, 90, 854

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 245 is 5 x 7 x 7

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 854 is 2 x 7 x 61

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, 245) = 27195

GCD(777, 245) = ( 777 x 245 ) / 27195

GCD(777, 245) = 190365 / 27195

GCD(777, 245) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 90

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

LCM(7, 90) = 630

GCD(7, 90) = ( 7 x 90 ) / 630

GCD(7, 90) = 630 / 630

GCD(7, 90) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 854

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

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

GCD(1, 854) = 854 / 854

GCD(1, 854) = 1

GCD of 777, 245, 90, 854 is 1
