Given Input Data is 285, 940, 872, 770

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

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 940 is 2 x 2 x 5 x 47

Prime Factorization of 872 is 2 x 2 x 2 x 109

Prime Factorization of 770 is 2 x 5 x 7 x 11

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(285, 940) = 53580

GCD(285, 940) = ( 285 x 940 ) / 53580

GCD(285, 940) = 267900 / 53580

GCD(285, 940) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 872

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

LCM(5, 872) = 4360

GCD(5, 872) = ( 5 x 872 ) / 4360

GCD(5, 872) = 4360 / 4360

GCD(5, 872) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 770

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

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

GCD(1, 770) = 770 / 770

GCD(1, 770) = 1

GCD of 285, 940, 872, 770 is 1
