Given Input Data is 255, 480, 139, 188

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

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 139 is 139

Prime Factorization of 188 is 2 x 2 x 47

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(255, 480) = 8160

GCD(255, 480) = ( 255 x 480 ) / 8160

GCD(255, 480) = 122400 / 8160

GCD(255, 480) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 139

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

LCM(15, 139) = 2085

GCD(15, 139) = ( 15 x 139 ) / 2085

GCD(15, 139) = 2085 / 2085

GCD(15, 139) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 188

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

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

GCD(1, 188) = 188 / 188

GCD(1, 188) = 1

GCD of 255, 480, 139, 188 is 1
