Given Input Data is 624, 930, 747, 845

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

Prime Factorization of 624 is 2 x 2 x 2 x 2 x 3 x 13

Prime Factorization of 930 is 2 x 3 x 5 x 31

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 845 is 5 x 13 x 13

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(624, 930) = 96720

GCD(624, 930) = ( 624 x 930 ) / 96720

GCD(624, 930) = 580320 / 96720

GCD(624, 930) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 747

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

LCM(6, 747) = 1494

GCD(6, 747) = ( 6 x 747 ) / 1494

GCD(6, 747) = 4482 / 1494

GCD(6, 747) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 845

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

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

GCD(3, 845) = 2535 / 2535

GCD(3, 845) = 1

GCD of 624, 930, 747, 845 is 1
