Given Input Data is 620, 555, 580, 659

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

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

Prime Factorization of 555 is 3 x 5 x 37

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

Prime Factorization of 659 is 659

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(620, 555) = 68820

GCD(620, 555) = ( 620 x 555 ) / 68820

GCD(620, 555) = 344100 / 68820

GCD(620, 555) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 580

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

LCM(5, 580) = 580

GCD(5, 580) = ( 5 x 580 ) / 580

GCD(5, 580) = 2900 / 580

GCD(5, 580) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 659

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

LCM(5, 659) = 3295

GCD(5, 659) = ( 5 x 659 ) / 3295

GCD(5, 659) = 3295 / 3295

GCD(5, 659) = 1

GCD of 620, 555, 580, 659 is 1
