Given Input Data is 447, 171, 137, 244

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 171 is 3 x 3 x 19

Prime Factorization of 137 is 137

Prime Factorization of 244 is 2 x 2 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(447, 171) = 25479

GCD(447, 171) = ( 447 x 171 ) / 25479

GCD(447, 171) = 76437 / 25479

GCD(447, 171) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 137

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

LCM(3, 137) = 411

GCD(3, 137) = ( 3 x 137 ) / 411

GCD(3, 137) = 411 / 411

GCD(3, 137) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 244

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

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

GCD(1, 244) = 244 / 244

GCD(1, 244) = 1

GCD of 447, 171, 137, 244 is 1
