Therefore, GCD of numbers 993, 255, 401, 203 is 1

Given Input Data is 993, 255, 401, 203

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

Prime Factorization of 993 is 3 x 331

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 401 is 401

Prime Factorization of 203 is 7 x 29

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(993, 255) = 84405

GCD(993, 255) = ( 993 x 255 ) / 84405

GCD(993, 255) = 253215 / 84405

GCD(993, 255) = 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 203

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

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

GCD(1, 203) = 203 / 203

GCD(1, 203) = 1

GCD of 993, 255, 401, 203 is 1
