Given Input Data is 636, 144, 83, 641

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 144 is 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 83 is 83

Prime Factorization of 641 is 641

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(636, 144) = 7632

GCD(636, 144) = ( 636 x 144 ) / 7632

GCD(636, 144) = 91584 / 7632

GCD(636, 144) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 83

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

LCM(12, 83) = 996

GCD(12, 83) = ( 12 x 83 ) / 996

GCD(12, 83) = 996 / 996

GCD(12, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 636, 144, 83, 641 is 1
