Given Input Data is 394, 172, 865, 461

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

Prime Factorization of 394 is 2 x 197

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 865 is 5 x 173

Prime Factorization of 461 is 461

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(394, 172) = 33884

GCD(394, 172) = ( 394 x 172 ) / 33884

GCD(394, 172) = 67768 / 33884

GCD(394, 172) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 865

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

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

GCD(2, 865) = 1730 / 1730

GCD(2, 865) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 461

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

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

GCD(1, 461) = 461 / 461

GCD(1, 461) = 1

GCD of 394, 172, 865, 461 is 1
