Given Input Data is 30, 267, 570, 549

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 267 is 3 x 89

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 549 is 3 x 3 x 61

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(30, 267) = 2670

GCD(30, 267) = ( 30 x 267 ) / 2670

GCD(30, 267) = 8010 / 2670

GCD(30, 267) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 570

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

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

GCD(3, 570) = 1710 / 570

GCD(3, 570) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 549

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

LCM(3, 549) = 549

GCD(3, 549) = ( 3 x 549 ) / 549

GCD(3, 549) = 1647 / 549

GCD(3, 549) = 3

GCD of 30, 267, 570, 549 is 3
