Given Input Data is 699, 813, 644, 585

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

Prime Factorization of 699 is 3 x 233

Prime Factorization of 813 is 3 x 271

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 585 is 3 x 3 x 5 x 13

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(699, 813) = 189429

GCD(699, 813) = ( 699 x 813 ) / 189429

GCD(699, 813) = 568287 / 189429

GCD(699, 813) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 644

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

LCM(3, 644) = 1932

GCD(3, 644) = ( 3 x 644 ) / 1932

GCD(3, 644) = 1932 / 1932

GCD(3, 644) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 585

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

LCM(1, 585) = 585

GCD(1, 585) = ( 1 x 585 ) / 585

GCD(1, 585) = 585 / 585

GCD(1, 585) = 1

GCD of 699, 813, 644, 585 is 1
