Therefore, GCD of numbers 611, 645, 417 is 1

Given Input Data is 611, 645, 417

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

Prime Factorization of 611 is 13 x 47

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 417 is 3 x 139

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(611, 645) = 394095

GCD(611, 645) = ( 611 x 645 ) / 394095

GCD(611, 645) = 394095 / 394095

GCD(611, 645) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 417

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

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

GCD(1, 417) = 417 / 417

GCD(1, 417) = 1

GCD of 611, 645, 417 is 1
