Given Input Data is 531, 810, 180, 278

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

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 278 is 2 x 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(531, 810) = 47790

GCD(531, 810) = ( 531 x 810 ) / 47790

GCD(531, 810) = 430110 / 47790

GCD(531, 810) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 180

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

LCM(9, 180) = 180

GCD(9, 180) = ( 9 x 180 ) / 180

GCD(9, 180) = 1620 / 180

GCD(9, 180) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 278

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

LCM(9, 278) = 2502

GCD(9, 278) = ( 9 x 278 ) / 2502

GCD(9, 278) = 2502 / 2502

GCD(9, 278) = 1

GCD of 531, 810, 180, 278 is 1
