Given Input Data is 637, 455, 569

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

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 569 is 569

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(637, 455) = 3185

GCD(637, 455) = ( 637 x 455 ) / 3185

GCD(637, 455) = 289835 / 3185

GCD(637, 455) = 91

Step2:

Here we consider the GCD from the above i.e. 91 as first number and the next as 569

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

LCM(91, 569) = 51779

GCD(91, 569) = ( 91 x 569 ) / 51779

GCD(91, 569) = 51779 / 51779

GCD(91, 569) = 1

GCD of 637, 455, 569 is 1
