Given Input Data is 912, 645, 620, 464

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

Prime Factorization of 912 is 2 x 2 x 2 x 2 x 3 x 19

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 464 is 2 x 2 x 2 x 2 x 29

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(912, 645) = 196080

GCD(912, 645) = ( 912 x 645 ) / 196080

GCD(912, 645) = 588240 / 196080

GCD(912, 645) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 620

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

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

GCD(3, 620) = 1860 / 1860

GCD(3, 620) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 464

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

LCM(1, 464) = 464

GCD(1, 464) = ( 1 x 464 ) / 464

GCD(1, 464) = 464 / 464

GCD(1, 464) = 1

GCD of 912, 645, 620, 464 is 1
