Therefore, GCD of numbers 870, 405, 412, 878 is 1

Given Input Data is 870, 405, 412, 878

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

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 412 is 2 x 2 x 103

Prime Factorization of 878 is 2 x 439

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(870, 405) = 23490

GCD(870, 405) = ( 870 x 405 ) / 23490

GCD(870, 405) = 352350 / 23490

GCD(870, 405) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 412

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

LCM(15, 412) = 6180

GCD(15, 412) = ( 15 x 412 ) / 6180

GCD(15, 412) = 6180 / 6180

GCD(15, 412) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 878

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

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

GCD(1, 878) = 878 / 878

GCD(1, 878) = 1

GCD of 870, 405, 412, 878 is 1
