Therefore, GCD of numbers 694, 630, 800, 611 is 1

Given Input Data is 694, 630, 800, 611

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

Prime Factorization of 694 is 2 x 347

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

Prime Factorization of 800 is 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 611 is 13 x 47

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(694, 630) = 218610

GCD(694, 630) = ( 694 x 630 ) / 218610

GCD(694, 630) = 437220 / 218610

GCD(694, 630) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 800

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

LCM(2, 800) = 800

GCD(2, 800) = ( 2 x 800 ) / 800

GCD(2, 800) = 1600 / 800

GCD(2, 800) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 611

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

LCM(2, 611) = 1222

GCD(2, 611) = ( 2 x 611 ) / 1222

GCD(2, 611) = 1222 / 1222

GCD(2, 611) = 1

GCD of 694, 630, 800, 611 is 1
