Therefore, GCD of numbers 479, 579, 398, 860 is 1

Given Input Data is 479, 579, 398, 860

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

Prime Factorization of 479 is 479

Prime Factorization of 579 is 3 x 193

Prime Factorization of 398 is 2 x 199

Prime Factorization of 860 is 2 x 2 x 5 x 43

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, 579) = 277341

GCD(479, 579) = ( 479 x 579 ) / 277341

GCD(479, 579) = 277341 / 277341

GCD(479, 579) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 398

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

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

GCD(1, 398) = 398 / 398

GCD(1, 398) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 860

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

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

GCD(1, 860) = 860 / 860

GCD(1, 860) = 1

GCD of 479, 579, 398, 860 is 1
