Given Input Data is 27, 903, 860, 408

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

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17

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(27, 903) = 8127

GCD(27, 903) = ( 27 x 903 ) / 8127

GCD(27, 903) = 24381 / 8127

GCD(27, 903) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 860

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

LCM(3, 860) = 2580

GCD(3, 860) = ( 3 x 860 ) / 2580

GCD(3, 860) = 2580 / 2580

GCD(3, 860) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 408

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

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

GCD(1, 408) = 408 / 408

GCD(1, 408) = 1

GCD of 27, 903, 860, 408 is 1
