Given Input Data is 275, 891, 49, 297

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

Prime Factorization of 275 is 5 x 5 x 11

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 297 is 3 x 3 x 3 x 11

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(275, 891) = 22275

GCD(275, 891) = ( 275 x 891 ) / 22275

GCD(275, 891) = 245025 / 22275

GCD(275, 891) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 49

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

LCM(11, 49) = 539

GCD(11, 49) = ( 11 x 49 ) / 539

GCD(11, 49) = 539 / 539

GCD(11, 49) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 297

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

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

GCD(1, 297) = 297 / 297

GCD(1, 297) = 1

GCD of 275, 891, 49, 297 is 1
