Given Input Data is 665, 581, 419, 440

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 581 is 7 x 83

Prime Factorization of 419 is 419

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

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(665, 581) = 55195

GCD(665, 581) = ( 665 x 581 ) / 55195

GCD(665, 581) = 386365 / 55195

GCD(665, 581) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 419

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

LCM(7, 419) = 2933

GCD(7, 419) = ( 7 x 419 ) / 2933

GCD(7, 419) = 2933 / 2933

GCD(7, 419) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 440

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

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

GCD(1, 440) = 440 / 440

GCD(1, 440) = 1

GCD of 665, 581, 419, 440 is 1
