Given Input Data is 81, 897, 804, 511

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

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 897 is 3 x 13 x 23

Prime Factorization of 804 is 2 x 2 x 3 x 67

Prime Factorization of 511 is 7 x 73

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(81, 897) = 24219

GCD(81, 897) = ( 81 x 897 ) / 24219

GCD(81, 897) = 72657 / 24219

GCD(81, 897) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 804

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

LCM(3, 804) = 804

GCD(3, 804) = ( 3 x 804 ) / 804

GCD(3, 804) = 2412 / 804

GCD(3, 804) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 511

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

LCM(3, 511) = 1533

GCD(3, 511) = ( 3 x 511 ) / 1533

GCD(3, 511) = 1533 / 1533

GCD(3, 511) = 1

GCD of 81, 897, 804, 511 is 1
