Therefore, GCD of numbers 286, 390, 411 is 1

Given Input Data is 286, 390, 411

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

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 411 is 3 x 137

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(286, 390) = 4290

GCD(286, 390) = ( 286 x 390 ) / 4290

GCD(286, 390) = 111540 / 4290

GCD(286, 390) = 26

Step2:

Here we consider the GCD from the above i.e. 26 as first number and the next as 411

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

LCM(26, 411) = 10686

GCD(26, 411) = ( 26 x 411 ) / 10686

GCD(26, 411) = 10686 / 10686

GCD(26, 411) = 1

GCD of 286, 390, 411 is 1
