Given Input Data is 402, 450, 394, 187

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

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 394 is 2 x 197

Prime Factorization of 187 is 11 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(402, 450) = 30150

GCD(402, 450) = ( 402 x 450 ) / 30150

GCD(402, 450) = 180900 / 30150

GCD(402, 450) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 394

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

LCM(6, 394) = 1182

GCD(6, 394) = ( 6 x 394 ) / 1182

GCD(6, 394) = 2364 / 1182

GCD(6, 394) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 187

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

LCM(2, 187) = 374

GCD(2, 187) = ( 2 x 187 ) / 374

GCD(2, 187) = 374 / 374

GCD(2, 187) = 1

GCD of 402, 450, 394, 187 is 1
