Therefore, GCD of numbers 479, 641, 978, 706 is 1

Given Input Data is 479, 641, 978, 706

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

Prime Factorization of 479 is 479

Prime Factorization of 641 is 641

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 706 is 2 x 353

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, 641) = 307039

GCD(479, 641) = ( 479 x 641 ) / 307039

GCD(479, 641) = 307039 / 307039

GCD(479, 641) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 978

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

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

GCD(1, 978) = 978 / 978

GCD(1, 978) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 706

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

LCM(1, 706) = 706

GCD(1, 706) = ( 1 x 706 ) / 706

GCD(1, 706) = 706 / 706

GCD(1, 706) = 1

GCD of 479, 641, 978, 706 is 1
