So the Greatest Common Divisior 480, 485, 620, 421 is 1.

Therefore, GCD of numbers 480, 485, 620, 421 is 1

Given Input Data is 480, 485, 620, 421

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

Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 485 is 5 x 97

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 421 is 421

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(480, 485) = 46560

GCD(480, 485) = ( 480 x 485 ) / 46560

GCD(480, 485) = 232800 / 46560

GCD(480, 485) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 620

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

LCM(5, 620) = 620

GCD(5, 620) = ( 5 x 620 ) / 620

GCD(5, 620) = 3100 / 620

GCD(5, 620) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 421

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

LCM(5, 421) = 2105

GCD(5, 421) = ( 5 x 421 ) / 2105

GCD(5, 421) = 2105 / 2105

GCD(5, 421) = 1

GCD of 480, 485, 620, 421 is 1
