Given Input Data is 486, 921, 981, 328

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

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 921 is 3 x 307

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 328 is 2 x 2 x 2 x 41

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(486, 921) = 149202

GCD(486, 921) = ( 486 x 921 ) / 149202

GCD(486, 921) = 447606 / 149202

GCD(486, 921) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 981

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

LCM(3, 981) = 981

GCD(3, 981) = ( 3 x 981 ) / 981

GCD(3, 981) = 2943 / 981

GCD(3, 981) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 328

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

LCM(3, 328) = 984

GCD(3, 328) = ( 3 x 328 ) / 984

GCD(3, 328) = 984 / 984

GCD(3, 328) = 1

GCD of 486, 921, 981, 328 is 1
