Therefore, GCD of numbers 570, 830, 11, 657 is 1

Given Input Data is 570, 830, 11, 657

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 11 is 11

Prime Factorization of 657 is 3 x 3 x 73

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(570, 830) = 47310

GCD(570, 830) = ( 570 x 830 ) / 47310

GCD(570, 830) = 473100 / 47310

GCD(570, 830) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 11

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

LCM(10, 11) = 110

GCD(10, 11) = ( 10 x 11 ) / 110

GCD(10, 11) = 110 / 110

GCD(10, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 657

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

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

GCD(1, 657) = 657 / 657

GCD(1, 657) = 1

GCD of 570, 830, 11, 657 is 1
