Given Input Data is 558, 620, 659

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

Prime Factorization of 558 is 2 x 3 x 3 x 31

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

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(558, 620) = 5580

GCD(558, 620) = ( 558 x 620 ) / 5580

GCD(558, 620) = 345960 / 5580

GCD(558, 620) = 62

Step2:

Here we consider the GCD from the above i.e. 62 as first number and the next as 659

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

LCM(62, 659) = 40858

GCD(62, 659) = ( 62 x 659 ) / 40858

GCD(62, 659) = 40858 / 40858

GCD(62, 659) = 1

GCD of 558, 620, 659 is 1
