Given Input Data is 651, 847, 645, 584

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 584 is 2 x 2 x 2 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(651, 847) = 78771

GCD(651, 847) = ( 651 x 847 ) / 78771

GCD(651, 847) = 551397 / 78771

GCD(651, 847) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 645

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

LCM(7, 645) = 4515

GCD(7, 645) = ( 7 x 645 ) / 4515

GCD(7, 645) = 4515 / 4515

GCD(7, 645) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 584

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

LCM(1, 584) = 584

GCD(1, 584) = ( 1 x 584 ) / 584

GCD(1, 584) = 584 / 584

GCD(1, 584) = 1

GCD of 651, 847, 645, 584 is 1
