Therefore, GCD of numbers 861, 684, 33, 797 is 1

Given Input Data is 861, 684, 33, 797

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

Prime Factorization of 33 is 3 x 11

Prime Factorization of 797 is 797

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(861, 684) = 196308

GCD(861, 684) = ( 861 x 684 ) / 196308

GCD(861, 684) = 588924 / 196308

GCD(861, 684) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 33

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

LCM(3, 33) = 33

GCD(3, 33) = ( 3 x 33 ) / 33

GCD(3, 33) = 99 / 33

GCD(3, 33) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 797

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

LCM(3, 797) = 2391

GCD(3, 797) = ( 3 x 797 ) / 2391

GCD(3, 797) = 2391 / 2391

GCD(3, 797) = 1

GCD of 861, 684, 33, 797 is 1
