Given Input Data is 560, 194, 257

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

Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 x 7

Prime Factorization of 194 is 2 x 97

Prime Factorization of 257 is 257

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(560, 194) = 54320

GCD(560, 194) = ( 560 x 194 ) / 54320

GCD(560, 194) = 108640 / 54320

GCD(560, 194) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 257

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

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

GCD(2, 257) = 514 / 514

GCD(2, 257) = 1

GCD of 560, 194, 257 is 1
