Given Input Data is 799, 527, 690, 645

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

Prime Factorization of 799 is 17 x 47

Prime Factorization of 527 is 17 x 31

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 645 is 3 x 5 x 43

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(799, 527) = 24769

GCD(799, 527) = ( 799 x 527 ) / 24769

GCD(799, 527) = 421073 / 24769

GCD(799, 527) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 690

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

LCM(17, 690) = 11730

GCD(17, 690) = ( 17 x 690 ) / 11730

GCD(17, 690) = 11730 / 11730

GCD(17, 690) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 645

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

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

GCD(1, 645) = 645 / 645

GCD(1, 645) = 1

GCD of 799, 527, 690, 645 is 1
