Given Input Data is 955, 545, 406, 439

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

Prime Factorization of 955 is 5 x 191

Prime Factorization of 545 is 5 x 109

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 439 is 439

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(955, 545) = 104095

GCD(955, 545) = ( 955 x 545 ) / 104095

GCD(955, 545) = 520475 / 104095

GCD(955, 545) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 406

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

LCM(5, 406) = 2030

GCD(5, 406) = ( 5 x 406 ) / 2030

GCD(5, 406) = 2030 / 2030

GCD(5, 406) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

GCD of 955, 545, 406, 439 is 1
