Given Input Data is 84, 644, 569, 492

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 569 is 569

Prime Factorization of 492 is 2 x 2 x 3 x 41

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(84, 644) = 1932

GCD(84, 644) = ( 84 x 644 ) / 1932

GCD(84, 644) = 54096 / 1932

GCD(84, 644) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 569

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

LCM(28, 569) = 15932

GCD(28, 569) = ( 28 x 569 ) / 15932

GCD(28, 569) = 15932 / 15932

GCD(28, 569) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 492

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

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

GCD(1, 492) = 492 / 492

GCD(1, 492) = 1

GCD of 84, 644, 569, 492 is 1
