Therefore, GCD of numbers 136, 260, 845, 870 is 1

Given Input Data is 136, 260, 845, 870

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

Prime Factorization of 136 is 2 x 2 x 2 x 17

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 870 is 2 x 3 x 5 x 29

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(136, 260) = 8840

GCD(136, 260) = ( 136 x 260 ) / 8840

GCD(136, 260) = 35360 / 8840

GCD(136, 260) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 845

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

LCM(4, 845) = 3380

GCD(4, 845) = ( 4 x 845 ) / 3380

GCD(4, 845) = 3380 / 3380

GCD(4, 845) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 870

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

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

GCD(1, 870) = 870 / 870

GCD(1, 870) = 1

GCD of 136, 260, 845, 870 is 1
