Given Input Data is 582, 855, 394, 991

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

Prime Factorization of 582 is 2 x 3 x 97

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 394 is 2 x 197

Prime Factorization of 991 is 991

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(582, 855) = 165870

GCD(582, 855) = ( 582 x 855 ) / 165870

GCD(582, 855) = 497610 / 165870

GCD(582, 855) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 394

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

LCM(3, 394) = 1182

GCD(3, 394) = ( 3 x 394 ) / 1182

GCD(3, 394) = 1182 / 1182

GCD(3, 394) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 991

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

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

GCD(1, 991) = 991 / 991

GCD(1, 991) = 1

GCD of 582, 855, 394, 991 is 1
