Given Input Data is 555, 669, 57, 659

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 669 is 3 x 223

Prime Factorization of 57 is 3 x 19

Prime Factorization of 659 is 659

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(555, 669) = 123765

GCD(555, 669) = ( 555 x 669 ) / 123765

GCD(555, 669) = 371295 / 123765

GCD(555, 669) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 57

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

LCM(3, 57) = 57

GCD(3, 57) = ( 3 x 57 ) / 57

GCD(3, 57) = 171 / 57

GCD(3, 57) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 659

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

LCM(3, 659) = 1977

GCD(3, 659) = ( 3 x 659 ) / 1977

GCD(3, 659) = 1977 / 1977

GCD(3, 659) = 1

GCD of 555, 669, 57, 659 is 1
