Therefore, GCD of numbers 477, 789, 213, 286 is 1

Given Input Data is 477, 789, 213, 286

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

Prime Factorization of 477 is 3 x 3 x 53

Prime Factorization of 789 is 3 x 263

Prime Factorization of 213 is 3 x 71

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(477, 789) = 125451

GCD(477, 789) = ( 477 x 789 ) / 125451

GCD(477, 789) = 376353 / 125451

GCD(477, 789) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 213

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

LCM(3, 213) = 213

GCD(3, 213) = ( 3 x 213 ) / 213

GCD(3, 213) = 639 / 213

GCD(3, 213) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 286

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

LCM(3, 286) = 858

GCD(3, 286) = ( 3 x 286 ) / 858

GCD(3, 286) = 858 / 858

GCD(3, 286) = 1

GCD of 477, 789, 213, 286 is 1
