Therefore, GCD of numbers 774, 747, 935, 855 is 1

Given Input Data is 774, 747, 935, 855

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

Prime Factorization of 774 is 2 x 3 x 3 x 43

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 935 is 5 x 11 x 17

Prime Factorization of 855 is 3 x 3 x 5 x 19

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(774, 747) = 64242

GCD(774, 747) = ( 774 x 747 ) / 64242

GCD(774, 747) = 578178 / 64242

GCD(774, 747) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 935

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

LCM(9, 935) = 8415

GCD(9, 935) = ( 9 x 935 ) / 8415

GCD(9, 935) = 8415 / 8415

GCD(9, 935) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 855

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

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

GCD(1, 855) = 855 / 855

GCD(1, 855) = 1

GCD of 774, 747, 935, 855 is 1
