Given Input Data is 845, 170, 784

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

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(845, 170) = 28730

GCD(845, 170) = ( 845 x 170 ) / 28730

GCD(845, 170) = 143650 / 28730

GCD(845, 170) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 784

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

LCM(5, 784) = 3920

GCD(5, 784) = ( 5 x 784 ) / 3920

GCD(5, 784) = 3920 / 3920

GCD(5, 784) = 1

GCD of 845, 170, 784 is 1
