Therefore, GCD of numbers 12, 891, 275, 547 is 1

Given Input Data is 12, 891, 275, 547

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

Prime Factorization of 12 is 2 x 2 x 3

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

Prime Factorization of 275 is 5 x 5 x 11

Prime Factorization of 547 is 547

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(12, 891) = 3564

GCD(12, 891) = ( 12 x 891 ) / 3564

GCD(12, 891) = 10692 / 3564

GCD(12, 891) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 275

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

LCM(3, 275) = 825

GCD(3, 275) = ( 3 x 275 ) / 825

GCD(3, 275) = 825 / 825

GCD(3, 275) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 547

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

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

GCD(1, 547) = 547 / 547

GCD(1, 547) = 1

GCD of 12, 891, 275, 547 is 1
