Therefore, GCD of numbers 426, 453, 18, 805 is 1

Given Input Data is 426, 453, 18, 805

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

Prime Factorization of 426 is 2 x 3 x 71

Prime Factorization of 453 is 3 x 151

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 805 is 5 x 7 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(426, 453) = 64326

GCD(426, 453) = ( 426 x 453 ) / 64326

GCD(426, 453) = 192978 / 64326

GCD(426, 453) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 18

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

LCM(3, 18) = 18

GCD(3, 18) = ( 3 x 18 ) / 18

GCD(3, 18) = 54 / 18

GCD(3, 18) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 805

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

LCM(3, 805) = 2415

GCD(3, 805) = ( 3 x 805 ) / 2415

GCD(3, 805) = 2415 / 2415

GCD(3, 805) = 1

GCD of 426, 453, 18, 805 is 1
