Therefore, GCD of numbers 877, 420, 191, 878 is 1

Given Input Data is 877, 420, 191, 878

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

Prime Factorization of 877 is 877

Prime Factorization of 420 is 2 x 2 x 3 x 5 x 7

Prime Factorization of 191 is 191

Prime Factorization of 878 is 2 x 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(877, 420) = 368340

GCD(877, 420) = ( 877 x 420 ) / 368340

GCD(877, 420) = 368340 / 368340

GCD(877, 420) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 191

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

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

GCD(1, 191) = 191 / 191

GCD(1, 191) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 878

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

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

GCD(1, 878) = 878 / 878

GCD(1, 878) = 1

GCD of 877, 420, 191, 878 is 1
