Therefore, GCD of numbers 570, 395, 19, 381 is 1

Given Input Data is 570, 395, 19, 381

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 395 is 5 x 79

Prime Factorization of 19 is 19

Prime Factorization of 381 is 3 x 127

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(570, 395) = 45030

GCD(570, 395) = ( 570 x 395 ) / 45030

GCD(570, 395) = 225150 / 45030

GCD(570, 395) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 19

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

LCM(5, 19) = 95

GCD(5, 19) = ( 5 x 19 ) / 95

GCD(5, 19) = 95 / 95

GCD(5, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 381

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

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

GCD(1, 381) = 381 / 381

GCD(1, 381) = 1

GCD of 570, 395, 19, 381 is 1
