Therefore, GCD of numbers 284, 646, 245 is 1

Given Input Data is 284, 646, 245

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

Prime Factorization of 284 is 2 x 2 x 71

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 245 is 5 x 7 x 7

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(284, 646) = 91732

GCD(284, 646) = ( 284 x 646 ) / 91732

GCD(284, 646) = 183464 / 91732

GCD(284, 646) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 245

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

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

GCD(2, 245) = 490 / 490

GCD(2, 245) = 1

GCD of 284, 646, 245 is 1
