Given Input Data is 790, 420, 933, 994

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

Prime Factorization of 790 is 2 x 5 x 79

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 933 is 3 x 311

Prime Factorization of 994 is 2 x 7 x 71

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(790, 420) = 33180

GCD(790, 420) = ( 790 x 420 ) / 33180

GCD(790, 420) = 331800 / 33180

GCD(790, 420) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 933

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

LCM(10, 933) = 9330

GCD(10, 933) = ( 10 x 933 ) / 9330

GCD(10, 933) = 9330 / 9330

GCD(10, 933) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 994

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

LCM(1, 994) = 994

GCD(1, 994) = ( 1 x 994 ) / 994

GCD(1, 994) = 994 / 994

GCD(1, 994) = 1

GCD of 790, 420, 933, 994 is 1
