Therefore, GCD of numbers 920, 630, 397, 808 is 1

Given Input Data is 920, 630, 397, 808

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

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

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

Prime Factorization of 397 is 397

Prime Factorization of 808 is 2 x 2 x 2 x 101

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(920, 630) = 57960

GCD(920, 630) = ( 920 x 630 ) / 57960

GCD(920, 630) = 579600 / 57960

GCD(920, 630) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 397

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

LCM(10, 397) = 3970

GCD(10, 397) = ( 10 x 397 ) / 3970

GCD(10, 397) = 3970 / 3970

GCD(10, 397) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 808

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

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

GCD(1, 808) = 808 / 808

GCD(1, 808) = 1

GCD of 920, 630, 397, 808 is 1
