Therefore, GCD of numbers 995, 605, 687, 503 is 1

Given Input Data is 995, 605, 687, 503

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

Prime Factorization of 995 is 5 x 199

Prime Factorization of 605 is 5 x 11 x 11

Prime Factorization of 687 is 3 x 229

Prime Factorization of 503 is 503

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(995, 605) = 120395

GCD(995, 605) = ( 995 x 605 ) / 120395

GCD(995, 605) = 601975 / 120395

GCD(995, 605) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 687

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

LCM(5, 687) = 3435

GCD(5, 687) = ( 5 x 687 ) / 3435

GCD(5, 687) = 3435 / 3435

GCD(5, 687) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 503

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

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

GCD(1, 503) = 503 / 503

GCD(1, 503) = 1

GCD of 995, 605, 687, 503 is 1
