Given Input Data is 891, 837, 36, 445

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

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

Prime Factorization of 837 is 3 x 3 x 3 x 31

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 445 is 5 x 89

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(891, 837) = 27621

GCD(891, 837) = ( 891 x 837 ) / 27621

GCD(891, 837) = 745767 / 27621

GCD(891, 837) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 36

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

LCM(27, 36) = 108

GCD(27, 36) = ( 27 x 36 ) / 108

GCD(27, 36) = 972 / 108

GCD(27, 36) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 445

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

LCM(9, 445) = 4005

GCD(9, 445) = ( 9 x 445 ) / 4005

GCD(9, 445) = 4005 / 4005

GCD(9, 445) = 1

GCD of 891, 837, 36, 445 is 1
