Therefore, GCD of numbers 511, 657, 830, 286 is 1

Given Input Data is 511, 657, 830, 286

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 286 is 2 x 11 x 13

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(511, 657) = 4599

GCD(511, 657) = ( 511 x 657 ) / 4599

GCD(511, 657) = 335727 / 4599

GCD(511, 657) = 73

Step2:

Here we consider the GCD from the above i.e. 73 as first number and the next as 830

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

LCM(73, 830) = 60590

GCD(73, 830) = ( 73 x 830 ) / 60590

GCD(73, 830) = 60590 / 60590

GCD(73, 830) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 286

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

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

GCD(1, 286) = 286 / 286

GCD(1, 286) = 1

GCD of 511, 657, 830, 286 is 1
