Given Input Data is 630, 222, 205, 280

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

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

Prime Factorization of 222 is 2 x 3 x 37

Prime Factorization of 205 is 5 x 41

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

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(630, 222) = 23310

GCD(630, 222) = ( 630 x 222 ) / 23310

GCD(630, 222) = 139860 / 23310

GCD(630, 222) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 205

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

LCM(6, 205) = 1230

GCD(6, 205) = ( 6 x 205 ) / 1230

GCD(6, 205) = 1230 / 1230

GCD(6, 205) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 280

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

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

GCD(1, 280) = 280 / 280

GCD(1, 280) = 1

GCD of 630, 222, 205, 280 is 1
