Given Input Data is 402, 783, 286

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

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 783 is 3 x 3 x 3 x 29

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(402, 783) = 104922

GCD(402, 783) = ( 402 x 783 ) / 104922

GCD(402, 783) = 314766 / 104922

GCD(402, 783) = 3

Step2:

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 402, 783, 286 is 1
