Given Input Data is 845, 286, 207

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 207 is 3 x 3 x 23

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(845, 286) = 18590

GCD(845, 286) = ( 845 x 286 ) / 18590

GCD(845, 286) = 241670 / 18590

GCD(845, 286) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 207

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

LCM(13, 207) = 2691

GCD(13, 207) = ( 13 x 207 ) / 2691

GCD(13, 207) = 2691 / 2691

GCD(13, 207) = 1

GCD of 845, 286, 207 is 1
