Therefore, GCD of numbers 555, 139, 689, 439 is 1

Given Input Data is 555, 139, 689, 439

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 139 is 139

Prime Factorization of 689 is 13 x 53

Prime Factorization of 439 is 439

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(555, 139) = 77145

GCD(555, 139) = ( 555 x 139 ) / 77145

GCD(555, 139) = 77145 / 77145

GCD(555, 139) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 689

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

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

GCD(1, 689) = 689 / 689

GCD(1, 689) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

GCD of 555, 139, 689, 439 is 1
