Given Input Data is 877, 209, 561, 862

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

Prime Factorization of 877 is 877

Prime Factorization of 209 is 11 x 19

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 862 is 2 x 431

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, 209) = 183293

GCD(877, 209) = ( 877 x 209 ) / 183293

GCD(877, 209) = 183293 / 183293

GCD(877, 209) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 561

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

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

GCD(1, 561) = 561 / 561

GCD(1, 561) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 862

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

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

GCD(1, 862) = 862 / 862

GCD(1, 862) = 1

GCD of 877, 209, 561, 862 is 1
