Therefore, GCD of numbers 111, 549, 197, 556 is 1

Given Input Data is 111, 549, 197, 556

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

Prime Factorization of 111 is 3 x 37

Prime Factorization of 549 is 3 x 3 x 61

Prime Factorization of 197 is 197

Prime Factorization of 556 is 2 x 2 x 139

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(111, 549) = 20313

GCD(111, 549) = ( 111 x 549 ) / 20313

GCD(111, 549) = 60939 / 20313

GCD(111, 549) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 197

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

LCM(3, 197) = 591

GCD(3, 197) = ( 3 x 197 ) / 591

GCD(3, 197) = 591 / 591

GCD(3, 197) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 556

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

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

GCD(1, 556) = 556 / 556

GCD(1, 556) = 1

GCD of 111, 549, 197, 556 is 1
