Therefore, GCD of numbers 27, 210, 401, 854 is 1

Given Input Data is 27, 210, 401, 854

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

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 401 is 401

Prime Factorization of 854 is 2 x 7 x 61

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(27, 210) = 1890

GCD(27, 210) = ( 27 x 210 ) / 1890

GCD(27, 210) = 5670 / 1890

GCD(27, 210) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 401

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

LCM(3, 401) = 1203

GCD(3, 401) = ( 3 x 401 ) / 1203

GCD(3, 401) = 1203 / 1203

GCD(3, 401) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 854

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

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

GCD(1, 854) = 854 / 854

GCD(1, 854) = 1

GCD of 27, 210, 401, 854 is 1
