Therefore, GCD of numbers 344, 256, 171, 406 is 1

Given Input Data is 344, 256, 171, 406

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

Prime Factorization of 344 is 2 x 2 x 2 x 43

Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 171 is 3 x 3 x 19

Prime Factorization of 406 is 2 x 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(344, 256) = 11008

GCD(344, 256) = ( 344 x 256 ) / 11008

GCD(344, 256) = 88064 / 11008

GCD(344, 256) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 171

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

LCM(8, 171) = 1368

GCD(8, 171) = ( 8 x 171 ) / 1368

GCD(8, 171) = 1368 / 1368

GCD(8, 171) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 406

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

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

GCD(1, 406) = 406 / 406

GCD(1, 406) = 1

GCD of 344, 256, 171, 406 is 1
