Given Input Data is 249, 837, 865, 880

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

Prime Factorization of 249 is 3 x 83

Prime Factorization of 837 is 3 x 3 x 3 x 31

Prime Factorization of 865 is 5 x 173

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

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(249, 837) = 69471

GCD(249, 837) = ( 249 x 837 ) / 69471

GCD(249, 837) = 208413 / 69471

GCD(249, 837) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 865

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

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

GCD(3, 865) = 2595 / 2595

GCD(3, 865) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 880

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

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

GCD(1, 880) = 880 / 880

GCD(1, 880) = 1

GCD of 249, 837, 865, 880 is 1
