Therefore, GCD of numbers 260, 845, 42, 864 is 1

Given Input Data is 260, 845, 42, 864

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

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 864 is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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(260, 845) = 3380

GCD(260, 845) = ( 260 x 845 ) / 3380

GCD(260, 845) = 219700 / 3380

GCD(260, 845) = 65

Step2:

Here we consider the GCD from the above i.e. 65 as first number and the next as 42

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

LCM(65, 42) = 2730

GCD(65, 42) = ( 65 x 42 ) / 2730

GCD(65, 42) = 2730 / 2730

GCD(65, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 864

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

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

GCD(1, 864) = 864 / 864

GCD(1, 864) = 1

GCD of 260, 845, 42, 864 is 1
