Given Input Data is 636, 400, 471

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 400 is 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 471 is 3 x 157

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, 400) = 63600

GCD(636, 400) = ( 636 x 400 ) / 63600

GCD(636, 400) = 254400 / 63600

GCD(636, 400) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 471

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

LCM(4, 471) = 1884

GCD(4, 471) = ( 4 x 471 ) / 1884

GCD(4, 471) = 1884 / 1884

GCD(4, 471) = 1

GCD of 636, 400, 471 is 1
