Given Input Data is 447, 636, 330, 253

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

Prime Factorization of 447 is 3 x 149

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

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 253 is 11 x 23

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(447, 636) = 94764

GCD(447, 636) = ( 447 x 636 ) / 94764

GCD(447, 636) = 284292 / 94764

GCD(447, 636) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 330

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

LCM(3, 330) = 330

GCD(3, 330) = ( 3 x 330 ) / 330

GCD(3, 330) = 990 / 330

GCD(3, 330) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 253

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

LCM(3, 253) = 759

GCD(3, 253) = ( 3 x 253 ) / 759

GCD(3, 253) = 759 / 759

GCD(3, 253) = 1

GCD of 447, 636, 330, 253 is 1
