Given Input Data is 447, 630, 403, 223

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

Prime Factorization of 447 is 3 x 149

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 403 is 13 x 31

Prime Factorization of 223 is 223

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, 630) = 93870

GCD(447, 630) = ( 447 x 630 ) / 93870

GCD(447, 630) = 281610 / 93870

GCD(447, 630) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 403

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

LCM(3, 403) = 1209

GCD(3, 403) = ( 3 x 403 ) / 1209

GCD(3, 403) = 1209 / 1209

GCD(3, 403) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 223

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

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

GCD(1, 223) = 223 / 223

GCD(1, 223) = 1

GCD of 447, 630, 403, 223 is 1
