Given Input Data is 66, 486, 543, 115

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

Prime Factorization of 66 is 2 x 3 x 11

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

Prime Factorization of 543 is 3 x 181

Prime Factorization of 115 is 5 x 23

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(66, 486) = 5346

GCD(66, 486) = ( 66 x 486 ) / 5346

GCD(66, 486) = 32076 / 5346

GCD(66, 486) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 543

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

LCM(6, 543) = 1086

GCD(6, 543) = ( 6 x 543 ) / 1086

GCD(6, 543) = 3258 / 1086

GCD(6, 543) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 115

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

LCM(3, 115) = 345

GCD(3, 115) = ( 3 x 115 ) / 345

GCD(3, 115) = 345 / 345

GCD(3, 115) = 1

GCD of 66, 486, 543, 115 is 1
