Therefore, GCD of numbers 817, 646, 311, 863 is 1

Given Input Data is 817, 646, 311, 863

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

Prime Factorization of 817 is 19 x 43

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 311 is 311

Prime Factorization of 863 is 863

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(817, 646) = 27778

GCD(817, 646) = ( 817 x 646 ) / 27778

GCD(817, 646) = 527782 / 27778

GCD(817, 646) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 311

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

LCM(19, 311) = 5909

GCD(19, 311) = ( 19 x 311 ) / 5909

GCD(19, 311) = 5909 / 5909

GCD(19, 311) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 863

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

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

GCD(1, 863) = 863 / 863

GCD(1, 863) = 1

GCD of 817, 646, 311, 863 is 1
