Therefore, GCD of numbers 436, 556, 278, 909 is 1

Given Input Data is 436, 556, 278, 909

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

Prime Factorization of 436 is 2 x 2 x 109

Prime Factorization of 556 is 2 x 2 x 139

Prime Factorization of 278 is 2 x 139

Prime Factorization of 909 is 3 x 3 x 101

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(436, 556) = 60604

GCD(436, 556) = ( 436 x 556 ) / 60604

GCD(436, 556) = 242416 / 60604

GCD(436, 556) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 278

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

LCM(4, 278) = 556

GCD(4, 278) = ( 4 x 278 ) / 556

GCD(4, 278) = 1112 / 556

GCD(4, 278) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 909

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

LCM(2, 909) = 1818

GCD(2, 909) = ( 2 x 909 ) / 1818

GCD(2, 909) = 1818 / 1818

GCD(2, 909) = 1

GCD of 436, 556, 278, 909 is 1
