Given Input Data is 773, 615, 81, 515

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

Prime Factorization of 773 is 773

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 515 is 5 x 103

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(773, 615) = 475395

GCD(773, 615) = ( 773 x 615 ) / 475395

GCD(773, 615) = 475395 / 475395

GCD(773, 615) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 515

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

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

GCD(1, 515) = 515 / 515

GCD(1, 515) = 1

GCD of 773, 615, 81, 515 is 1
