Therefore, GCD of numbers 63, 813, 395, 838 is 1

Given Input Data is 63, 813, 395, 838

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 813 is 3 x 271

Prime Factorization of 395 is 5 x 79

Prime Factorization of 838 is 2 x 419

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(63, 813) = 17073

GCD(63, 813) = ( 63 x 813 ) / 17073

GCD(63, 813) = 51219 / 17073

GCD(63, 813) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 395

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

LCM(3, 395) = 1185

GCD(3, 395) = ( 3 x 395 ) / 1185

GCD(3, 395) = 1185 / 1185

GCD(3, 395) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 838

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

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

GCD(1, 838) = 838 / 838

GCD(1, 838) = 1

GCD of 63, 813, 395, 838 is 1
