Given Input Data is 479, 290, 14, 858

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

Prime Factorization of 479 is 479

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 14 is 2 x 7

Prime Factorization of 858 is 2 x 3 x 11 x 13

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(479, 290) = 138910

GCD(479, 290) = ( 479 x 290 ) / 138910

GCD(479, 290) = 138910 / 138910

GCD(479, 290) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 14

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

LCM(1, 14) = 14

GCD(1, 14) = ( 1 x 14 ) / 14

GCD(1, 14) = 14 / 14

GCD(1, 14) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 858

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

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

GCD(1, 858) = 858 / 858

GCD(1, 858) = 1

GCD of 479, 290, 14, 858 is 1
