Given Input Data is 551, 494, 640

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

Prime Factorization of 551 is 19 x 29

Prime Factorization of 494 is 2 x 13 x 19

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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(551, 494) = 14326

GCD(551, 494) = ( 551 x 494 ) / 14326

GCD(551, 494) = 272194 / 14326

GCD(551, 494) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 640

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

LCM(19, 640) = 12160

GCD(19, 640) = ( 19 x 640 ) / 12160

GCD(19, 640) = 12160 / 12160

GCD(19, 640) = 1

GCD of 551, 494, 640 is 1
