Given Input Data is 407, 572, 455, 293

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

Prime Factorization of 407 is 11 x 37

Prime Factorization of 572 is 2 x 2 x 11 x 13

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 293 is 293

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(407, 572) = 21164

GCD(407, 572) = ( 407 x 572 ) / 21164

GCD(407, 572) = 232804 / 21164

GCD(407, 572) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 455

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

LCM(11, 455) = 5005

GCD(11, 455) = ( 11 x 455 ) / 5005

GCD(11, 455) = 5005 / 5005

GCD(11, 455) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 293

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

LCM(1, 293) = 293

GCD(1, 293) = ( 1 x 293 ) / 293

GCD(1, 293) = 293 / 293

GCD(1, 293) = 1

GCD of 407, 572, 455, 293 is 1
