Therefore, GCD of numbers 618, 648, 530, 995 is 1

Given Input Data is 618, 648, 530, 995

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 995 is 5 x 199

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(618, 648) = 66744

GCD(618, 648) = ( 618 x 648 ) / 66744

GCD(618, 648) = 400464 / 66744

GCD(618, 648) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 530

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

LCM(6, 530) = 1590

GCD(6, 530) = ( 6 x 530 ) / 1590

GCD(6, 530) = 3180 / 1590

GCD(6, 530) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 995

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

LCM(2, 995) = 1990

GCD(2, 995) = ( 2 x 995 ) / 1990

GCD(2, 995) = 1990 / 1990

GCD(2, 995) = 1

GCD of 618, 648, 530, 995 is 1
