Given Input Data is 444, 195, 654, 392

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

Prime Factorization of 444 is 2 x 2 x 3 x 37

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 654 is 2 x 3 x 109

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

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(444, 195) = 28860

GCD(444, 195) = ( 444 x 195 ) / 28860

GCD(444, 195) = 86580 / 28860

GCD(444, 195) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 654

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

LCM(3, 654) = 654

GCD(3, 654) = ( 3 x 654 ) / 654

GCD(3, 654) = 1962 / 654

GCD(3, 654) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 392

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

LCM(3, 392) = 1176

GCD(3, 392) = ( 3 x 392 ) / 1176

GCD(3, 392) = 1176 / 1176

GCD(3, 392) = 1

GCD of 444, 195, 654, 392 is 1
