Therefore, GCD of numbers 417, 321, 203, 454 is 1

Given Input Data is 417, 321, 203, 454

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

Prime Factorization of 417 is 3 x 139

Prime Factorization of 321 is 3 x 107

Prime Factorization of 203 is 7 x 29

Prime Factorization of 454 is 2 x 227

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(417, 321) = 44619

GCD(417, 321) = ( 417 x 321 ) / 44619

GCD(417, 321) = 133857 / 44619

GCD(417, 321) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 203

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

LCM(3, 203) = 609

GCD(3, 203) = ( 3 x 203 ) / 609

GCD(3, 203) = 609 / 609

GCD(3, 203) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 454

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

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

GCD(1, 454) = 454 / 454

GCD(1, 454) = 1

GCD of 417, 321, 203, 454 is 1
