Given Input Data is 630, 355, 483, 121

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 355 is 5 x 71

Prime Factorization of 483 is 3 x 7 x 23

Prime Factorization of 121 is 11 x 11

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, 355) = 44730

GCD(630, 355) = ( 630 x 355 ) / 44730

GCD(630, 355) = 223650 / 44730

GCD(630, 355) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 483

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

LCM(5, 483) = 2415

GCD(5, 483) = ( 5 x 483 ) / 2415

GCD(5, 483) = 2415 / 2415

GCD(5, 483) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 121

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

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

GCD(1, 121) = 121 / 121

GCD(1, 121) = 1

GCD of 630, 355, 483, 121 is 1
