Given Input Data is 380, 995, 23, 439

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

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 995 is 5 x 199

Prime Factorization of 23 is 23

Prime Factorization of 439 is 439

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(380, 995) = 75620

GCD(380, 995) = ( 380 x 995 ) / 75620

GCD(380, 995) = 378100 / 75620

GCD(380, 995) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 23

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

LCM(5, 23) = 115

GCD(5, 23) = ( 5 x 23 ) / 115

GCD(5, 23) = 115 / 115

GCD(5, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

GCD of 380, 995, 23, 439 is 1
