Given Input Data is 387, 279, 97, 354

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

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 279 is 3 x 3 x 31

Prime Factorization of 97 is 97

Prime Factorization of 354 is 2 x 3 x 59

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(387, 279) = 11997

GCD(387, 279) = ( 387 x 279 ) / 11997

GCD(387, 279) = 107973 / 11997

GCD(387, 279) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 97

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

LCM(9, 97) = 873

GCD(9, 97) = ( 9 x 97 ) / 873

GCD(9, 97) = 873 / 873

GCD(9, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 354

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

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

GCD(1, 354) = 354 / 354

GCD(1, 354) = 1

GCD of 387, 279, 97, 354 is 1
