Given Input Data is 663, 130, 255, 429

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 429 is 3 x 11 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(663, 130) = 6630

GCD(663, 130) = ( 663 x 130 ) / 6630

GCD(663, 130) = 86190 / 6630

GCD(663, 130) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 255

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

LCM(13, 255) = 3315

GCD(13, 255) = ( 13 x 255 ) / 3315

GCD(13, 255) = 3315 / 3315

GCD(13, 255) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 429

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

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

GCD(1, 429) = 429 / 429

GCD(1, 429) = 1

GCD of 663, 130, 255, 429 is 1
