Therefore, GCD of numbers 630, 605, 278, 612 is 1

Given Input Data is 630, 605, 278, 612

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 605 is 5 x 11 x 11

Prime Factorization of 278 is 2 x 139

Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17

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, 605) = 76230

GCD(630, 605) = ( 630 x 605 ) / 76230

GCD(630, 605) = 381150 / 76230

GCD(630, 605) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 278

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

LCM(5, 278) = 1390

GCD(5, 278) = ( 5 x 278 ) / 1390

GCD(5, 278) = 1390 / 1390

GCD(5, 278) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 612

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

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

GCD(1, 612) = 612 / 612

GCD(1, 612) = 1

GCD of 630, 605, 278, 612 is 1
