Given Input Data is 780, 692, 104, 477

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 692 is 2 x 2 x 173

Prime Factorization of 104 is 2 x 2 x 2 x 13

Prime Factorization of 477 is 3 x 3 x 53

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(780, 692) = 134940

GCD(780, 692) = ( 780 x 692 ) / 134940

GCD(780, 692) = 539760 / 134940

GCD(780, 692) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 104

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

LCM(4, 104) = 104

GCD(4, 104) = ( 4 x 104 ) / 104

GCD(4, 104) = 416 / 104

GCD(4, 104) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 477

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

LCM(4, 477) = 1908

GCD(4, 477) = ( 4 x 477 ) / 1908

GCD(4, 477) = 1908 / 1908

GCD(4, 477) = 1

GCD of 780, 692, 104, 477 is 1
