Given Input Data is 321, 885, 920, 395

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

Prime Factorization of 321 is 3 x 107

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 395 is 5 x 79

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(321, 885) = 94695

GCD(321, 885) = ( 321 x 885 ) / 94695

GCD(321, 885) = 284085 / 94695

GCD(321, 885) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 920

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

LCM(3, 920) = 2760

GCD(3, 920) = ( 3 x 920 ) / 2760

GCD(3, 920) = 2760 / 2760

GCD(3, 920) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 395

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

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

GCD(1, 395) = 395 / 395

GCD(1, 395) = 1

GCD of 321, 885, 920, 395 is 1
