Given Input Data is 840, 878, 94, 479

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 878 is 2 x 439

Prime Factorization of 94 is 2 x 47

Prime Factorization of 479 is 479

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(840, 878) = 368760

GCD(840, 878) = ( 840 x 878 ) / 368760

GCD(840, 878) = 737520 / 368760

GCD(840, 878) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 94

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

LCM(2, 94) = 94

GCD(2, 94) = ( 2 x 94 ) / 94

GCD(2, 94) = 188 / 94

GCD(2, 94) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 479

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

LCM(2, 479) = 958

GCD(2, 479) = ( 2 x 479 ) / 958

GCD(2, 479) = 958 / 958

GCD(2, 479) = 1

GCD of 840, 878, 94, 479 is 1
