Given Input Data is 581, 770, 805, 538

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

Prime Factorization of 581 is 7 x 83

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 538 is 2 x 269

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(581, 770) = 63910

GCD(581, 770) = ( 581 x 770 ) / 63910

GCD(581, 770) = 447370 / 63910

GCD(581, 770) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 805

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

LCM(7, 805) = 805

GCD(7, 805) = ( 7 x 805 ) / 805

GCD(7, 805) = 5635 / 805

GCD(7, 805) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 538

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

LCM(7, 538) = 3766

GCD(7, 538) = ( 7 x 538 ) / 3766

GCD(7, 538) = 3766 / 3766

GCD(7, 538) = 1

GCD of 581, 770, 805, 538 is 1
