Therefore, GCD of numbers 39, 381, 842, 127 is 1

Given Input Data is 39, 381, 842, 127

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 381 is 3 x 127

Prime Factorization of 842 is 2 x 421

Prime Factorization of 127 is 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(39, 381) = 4953

GCD(39, 381) = ( 39 x 381 ) / 4953

GCD(39, 381) = 14859 / 4953

GCD(39, 381) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 842

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

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

GCD(3, 842) = 2526 / 2526

GCD(3, 842) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 127

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

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

GCD(1, 127) = 127 / 127

GCD(1, 127) = 1

GCD of 39, 381, 842, 127 is 1
