Therefore, GCD of numbers 878, 434, 40, 885 is 1

Given Input Data is 878, 434, 40, 885

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

Prime Factorization of 878 is 2 x 439

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 885 is 3 x 5 x 59

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(878, 434) = 190526

GCD(878, 434) = ( 878 x 434 ) / 190526

GCD(878, 434) = 381052 / 190526

GCD(878, 434) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 40

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

LCM(2, 40) = 40

GCD(2, 40) = ( 2 x 40 ) / 40

GCD(2, 40) = 80 / 40

GCD(2, 40) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 885

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

LCM(2, 885) = 1770

GCD(2, 885) = ( 2 x 885 ) / 1770

GCD(2, 885) = 1770 / 1770

GCD(2, 885) = 1

GCD of 878, 434, 40, 885 is 1
