Therefore, GCD of numbers 813, 363, 377, 857 is 1

Given Input Data is 813, 363, 377, 857

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

Prime Factorization of 813 is 3 x 271

Prime Factorization of 363 is 3 x 11 x 11

Prime Factorization of 377 is 13 x 29

Prime Factorization of 857 is 857

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(813, 363) = 98373

GCD(813, 363) = ( 813 x 363 ) / 98373

GCD(813, 363) = 295119 / 98373

GCD(813, 363) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 377

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

LCM(3, 377) = 1131

GCD(3, 377) = ( 3 x 377 ) / 1131

GCD(3, 377) = 1131 / 1131

GCD(3, 377) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 857

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

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

GCD(1, 857) = 857 / 857

GCD(1, 857) = 1

GCD of 813, 363, 377, 857 is 1
