Therefore, GCD of numbers 287, 385, 286 is 1

Given Input Data is 287, 385, 286

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

Prime Factorization of 287 is 7 x 41

Prime Factorization of 385 is 5 x 7 x 11

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(287, 385) = 15785

GCD(287, 385) = ( 287 x 385 ) / 15785

GCD(287, 385) = 110495 / 15785

GCD(287, 385) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 286

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

LCM(7, 286) = 2002

GCD(7, 286) = ( 7 x 286 ) / 2002

GCD(7, 286) = 2002 / 2002

GCD(7, 286) = 1

GCD of 287, 385, 286 is 1
