Given Input Data is 945, 873, 19, 773

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

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 873 is 3 x 3 x 97

Prime Factorization of 19 is 19

Prime Factorization of 773 is 773

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(945, 873) = 91665

GCD(945, 873) = ( 945 x 873 ) / 91665

GCD(945, 873) = 824985 / 91665

GCD(945, 873) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 19

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

LCM(9, 19) = 171

GCD(9, 19) = ( 9 x 19 ) / 171

GCD(9, 19) = 171 / 171

GCD(9, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 773

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

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

GCD(1, 773) = 773 / 773

GCD(1, 773) = 1

GCD of 945, 873, 19, 773 is 1
