Therefore, GCD of numbers 834, 891, 684, 788 is 1

Given Input Data is 834, 891, 684, 788

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

Prime Factorization of 834 is 2 x 3 x 139

Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11

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

Prime Factorization of 788 is 2 x 2 x 197

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(834, 891) = 247698

GCD(834, 891) = ( 834 x 891 ) / 247698

GCD(834, 891) = 743094 / 247698

GCD(834, 891) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 684

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

LCM(3, 684) = 684

GCD(3, 684) = ( 3 x 684 ) / 684

GCD(3, 684) = 2052 / 684

GCD(3, 684) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 788

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

LCM(3, 788) = 2364

GCD(3, 788) = ( 3 x 788 ) / 2364

GCD(3, 788) = 2364 / 2364

GCD(3, 788) = 1

GCD of 834, 891, 684, 788 is 1
