Therefore, GCD of numbers 810, 978, 41, 878 is 1

Given Input Data is 810, 978, 41, 878

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

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 41 is 41

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(810, 978) = 132030

GCD(810, 978) = ( 810 x 978 ) / 132030

GCD(810, 978) = 792180 / 132030

GCD(810, 978) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 41

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

LCM(6, 41) = 246

GCD(6, 41) = ( 6 x 41 ) / 246

GCD(6, 41) = 246 / 246

GCD(6, 41) = 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 810, 978, 41, 878 is 1
