Given Input Data is 605, 630, 983, 440

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

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 983 is 983

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(605, 630) = 76230

GCD(605, 630) = ( 605 x 630 ) / 76230

GCD(605, 630) = 381150 / 76230

GCD(605, 630) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 983

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

LCM(5, 983) = 4915

GCD(5, 983) = ( 5 x 983 ) / 4915

GCD(5, 983) = 4915 / 4915

GCD(5, 983) = 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 605, 630, 983, 440 is 1
