Given Input Data is 396, 253, 851

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

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

Prime Factorization of 253 is 11 x 23

Prime Factorization of 851 is 23 x 37

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(396, 253) = 9108

GCD(396, 253) = ( 396 x 253 ) / 9108

GCD(396, 253) = 100188 / 9108

GCD(396, 253) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 851

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

LCM(11, 851) = 9361

GCD(11, 851) = ( 11 x 851 ) / 9361

GCD(11, 851) = 9361 / 9361

GCD(11, 851) = 1

GCD of 396, 253, 851 is 1
