Therefore, GCD of numbers 99, 78, 97, 71 is 1

Given Input Data is 99, 78, 97, 71

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

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 97 is 97

Prime Factorization of 71 is 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(99, 78) = 2574

GCD(99, 78) = ( 99 x 78 ) / 2574

GCD(99, 78) = 7722 / 2574

GCD(99, 78) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 97

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

LCM(3, 97) = 291

GCD(3, 97) = ( 3 x 97 ) / 291

GCD(3, 97) = 291 / 291

GCD(3, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

GCD of 99, 78, 97, 71 is 1
