We found the divisors of 115, 713, 204, 778 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 115, 713, 204, 778 is 1.

Therefore, GCD of numbers 115, 713, 204, 778 is 1

Given Input Data is 115, 713, 204, 778

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

Prime Factorization of 115 is 5 x 23

Prime Factorization of 713 is 23 x 31

Prime Factorization of 204 is 2 x 2 x 3 x 17

Prime Factorization of 778 is 2 x 389

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(115, 713) = 3565

GCD(115, 713) = ( 115 x 713 ) / 3565

GCD(115, 713) = 81995 / 3565

GCD(115, 713) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 204

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

LCM(23, 204) = 4692

GCD(23, 204) = ( 23 x 204 ) / 4692

GCD(23, 204) = 4692 / 4692

GCD(23, 204) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 778

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

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

GCD(1, 778) = 778 / 778

GCD(1, 778) = 1

GCD of 115, 713, 204, 778 is 1
