Given Input Data is 424, 218, 247

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

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 218 is 2 x 109

Prime Factorization of 247 is 13 x 19

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(424, 218) = 46216

GCD(424, 218) = ( 424 x 218 ) / 46216

GCD(424, 218) = 92432 / 46216

GCD(424, 218) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 247

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

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

GCD(2, 247) = 494 / 494

GCD(2, 247) = 1

GCD of 424, 218, 247 is 1
