Therefore, GCD of numbers 830, 640, 89, 618 is 1

Given Input Data is 830, 640, 89, 618

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

Prime Factorization of 830 is 2 x 5 x 83

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

Prime Factorization of 89 is 89

Prime Factorization of 618 is 2 x 3 x 103

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(830, 640) = 53120

GCD(830, 640) = ( 830 x 640 ) / 53120

GCD(830, 640) = 531200 / 53120

GCD(830, 640) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 89

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

LCM(10, 89) = 890

GCD(10, 89) = ( 10 x 89 ) / 890

GCD(10, 89) = 890 / 890

GCD(10, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 618

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

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

GCD(1, 618) = 618 / 618

GCD(1, 618) = 1

GCD of 830, 640, 89, 618 is 1
