Given Input Data is 580, 845, 397

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

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 397 is 397

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(580, 845) = 98020

GCD(580, 845) = ( 580 x 845 ) / 98020

GCD(580, 845) = 490100 / 98020

GCD(580, 845) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 397

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

LCM(5, 397) = 1985

GCD(5, 397) = ( 5 x 397 ) / 1985

GCD(5, 397) = 1985 / 1985

GCD(5, 397) = 1

GCD of 580, 845, 397 is 1
