Given Input Data is 486, 279, 216, 530

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

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 279 is 3 x 3 x 31

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 530 is 2 x 5 x 53

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(486, 279) = 15066

GCD(486, 279) = ( 486 x 279 ) / 15066

GCD(486, 279) = 135594 / 15066

GCD(486, 279) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 216

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

LCM(9, 216) = 216

GCD(9, 216) = ( 9 x 216 ) / 216

GCD(9, 216) = 1944 / 216

GCD(9, 216) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 530

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

LCM(9, 530) = 4770

GCD(9, 530) = ( 9 x 530 ) / 4770

GCD(9, 530) = 4770 / 4770

GCD(9, 530) = 1

GCD of 486, 279, 216, 530 is 1
