Therefore, GCD of numbers 630, 297, 833, 640 is 1

Given Input Data is 630, 297, 833, 640

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 297 is 3 x 3 x 3 x 11

Prime Factorization of 833 is 7 x 7 x 17

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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, 297) = 20790

GCD(630, 297) = ( 630 x 297 ) / 20790

GCD(630, 297) = 187110 / 20790

GCD(630, 297) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 833

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

LCM(9, 833) = 7497

GCD(9, 833) = ( 9 x 833 ) / 7497

GCD(9, 833) = 7497 / 7497

GCD(9, 833) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 640

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

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

GCD(1, 640) = 640 / 640

GCD(1, 640) = 1

GCD of 630, 297, 833, 640 is 1
