Given Input Data is 579, 117, 27, 655

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

Prime Factorization of 579 is 3 x 193

Prime Factorization of 117 is 3 x 3 x 13

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 655 is 5 x 131

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(579, 117) = 22581

GCD(579, 117) = ( 579 x 117 ) / 22581

GCD(579, 117) = 67743 / 22581

GCD(579, 117) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 27

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

LCM(3, 27) = 27

GCD(3, 27) = ( 3 x 27 ) / 27

GCD(3, 27) = 81 / 27

GCD(3, 27) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 655

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

LCM(3, 655) = 1965

GCD(3, 655) = ( 3 x 655 ) / 1965

GCD(3, 655) = 1965 / 1965

GCD(3, 655) = 1

GCD of 579, 117, 27, 655 is 1
