Therefore, GCD of numbers 310, 155, 556, 843 is 1

Given Input Data is 310, 155, 556, 843

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

Prime Factorization of 310 is 2 x 5 x 31

Prime Factorization of 155 is 5 x 31

Prime Factorization of 556 is 2 x 2 x 139

Prime Factorization of 843 is 3 x 281

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(310, 155) = 310

GCD(310, 155) = ( 310 x 155 ) / 310

GCD(310, 155) = 48050 / 310

GCD(310, 155) = 155

Step2:

Here we consider the GCD from the above i.e. 155 as first number and the next as 556

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

LCM(155, 556) = 86180

GCD(155, 556) = ( 155 x 556 ) / 86180

GCD(155, 556) = 86180 / 86180

GCD(155, 556) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 843

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

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

GCD(1, 843) = 843 / 843

GCD(1, 843) = 1

GCD of 310, 155, 556, 843 is 1
