Given Input Data is 750, 770, 285, 139

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

Prime Factorization of 750 is 2 x 3 x 5 x 5 x 5

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

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 139 is 139

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(750, 770) = 57750

GCD(750, 770) = ( 750 x 770 ) / 57750

GCD(750, 770) = 577500 / 57750

GCD(750, 770) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 285

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

LCM(10, 285) = 570

GCD(10, 285) = ( 10 x 285 ) / 570

GCD(10, 285) = 2850 / 570

GCD(10, 285) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 139

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

LCM(5, 139) = 695

GCD(5, 139) = ( 5 x 139 ) / 695

GCD(5, 139) = 695 / 695

GCD(5, 139) = 1

GCD of 750, 770, 285, 139 is 1
