Therefore, GCD of numbers 18, 426, 140, 913 is 1

Given Input Data is 18, 426, 140, 913

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 426 is 2 x 3 x 71

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 913 is 11 x 83

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(18, 426) = 1278

GCD(18, 426) = ( 18 x 426 ) / 1278

GCD(18, 426) = 7668 / 1278

GCD(18, 426) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 140

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

LCM(6, 140) = 420

GCD(6, 140) = ( 6 x 140 ) / 420

GCD(6, 140) = 840 / 420

GCD(6, 140) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 913

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

LCM(2, 913) = 1826

GCD(2, 913) = ( 2 x 913 ) / 1826

GCD(2, 913) = 1826 / 1826

GCD(2, 913) = 1

GCD of 18, 426, 140, 913 is 1
