We found the divisors of 813, 712, 404, 785 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 813, 712, 404, 785 is 1.

Therefore, GCD of numbers 813, 712, 404, 785 is 1

Given Input Data is 813, 712, 404, 785

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

Prime Factorization of 813 is 3 x 271

Prime Factorization of 712 is 2 x 2 x 2 x 89

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 785 is 5 x 157

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, 712) = 578856

GCD(813, 712) = ( 813 x 712 ) / 578856

GCD(813, 712) = 578856 / 578856

GCD(813, 712) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 404

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

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

GCD(1, 404) = 404 / 404

GCD(1, 404) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 785

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

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

GCD(1, 785) = 785 / 785

GCD(1, 785) = 1

GCD of 813, 712, 404, 785 is 1
