Therefore, GCD of numbers 618, 428, 22, 247 is 1

Given Input Data is 618, 428, 22, 247

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 22 is 2 x 11

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(618, 428) = 132252

GCD(618, 428) = ( 618 x 428 ) / 132252

GCD(618, 428) = 264504 / 132252

GCD(618, 428) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 22

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

LCM(2, 22) = 22

GCD(2, 22) = ( 2 x 22 ) / 22

GCD(2, 22) = 44 / 22

GCD(2, 22) = 2

Step3:

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 618, 428, 22, 247 is 1
