Given Input Data is 446, 388, 28, 641

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

Prime Factorization of 446 is 2 x 223

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 641 is 641

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(446, 388) = 86524

GCD(446, 388) = ( 446 x 388 ) / 86524

GCD(446, 388) = 173048 / 86524

GCD(446, 388) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 28

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

LCM(2, 28) = 28

GCD(2, 28) = ( 2 x 28 ) / 28

GCD(2, 28) = 56 / 28

GCD(2, 28) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 641

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

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

GCD(2, 641) = 1282 / 1282

GCD(2, 641) = 1

GCD of 446, 388, 28, 641 is 1
