Given Input Data is 270, 819, 10, 543

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

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 10 is 2 x 5

Prime Factorization of 543 is 3 x 181

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(270, 819) = 24570

GCD(270, 819) = ( 270 x 819 ) / 24570

GCD(270, 819) = 221130 / 24570

GCD(270, 819) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 10

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

LCM(9, 10) = 90

GCD(9, 10) = ( 9 x 10 ) / 90

GCD(9, 10) = 90 / 90

GCD(9, 10) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 543

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

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

GCD(1, 543) = 543 / 543

GCD(1, 543) = 1

GCD of 270, 819, 10, 543 is 1
