Given Input Data is 669, 264, 566, 390

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

Prime Factorization of 669 is 3 x 223

Prime Factorization of 264 is 2 x 2 x 2 x 3 x 11

Prime Factorization of 566 is 2 x 283

Prime Factorization of 390 is 2 x 3 x 5 x 13

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(669, 264) = 58872

GCD(669, 264) = ( 669 x 264 ) / 58872

GCD(669, 264) = 176616 / 58872

GCD(669, 264) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 566

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

LCM(3, 566) = 1698

GCD(3, 566) = ( 3 x 566 ) / 1698

GCD(3, 566) = 1698 / 1698

GCD(3, 566) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 390

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

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

GCD(1, 390) = 390 / 390

GCD(1, 390) = 1

GCD of 669, 264, 566, 390 is 1
