Therefore, GCD of numbers 819, 791, 97, 805 is 1

Given Input Data is 819, 791, 97, 805

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

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 791 is 7 x 113

Prime Factorization of 97 is 97

Prime Factorization of 805 is 5 x 7 x 23

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(819, 791) = 92547

GCD(819, 791) = ( 819 x 791 ) / 92547

GCD(819, 791) = 647829 / 92547

GCD(819, 791) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 97

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

LCM(7, 97) = 679

GCD(7, 97) = ( 7 x 97 ) / 679

GCD(7, 97) = 679 / 679

GCD(7, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 805

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

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

GCD(1, 805) = 805 / 805

GCD(1, 805) = 1

GCD of 819, 791, 97, 805 is 1
