Therefore, GCD of numbers 747, 190, 457, 818 is 1

Given Input Data is 747, 190, 457, 818

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

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 457 is 457

Prime Factorization of 818 is 2 x 409

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(747, 190) = 141930

GCD(747, 190) = ( 747 x 190 ) / 141930

GCD(747, 190) = 141930 / 141930

GCD(747, 190) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 457

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

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

GCD(1, 457) = 457 / 457

GCD(1, 457) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 818

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

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

GCD(1, 818) = 818 / 818

GCD(1, 818) = 1

GCD of 747, 190, 457, 818 is 1
