Greatest Common Divisior
We found the divisors of 278, 683, 205, 810 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 278, 683, 205, 810 is 1.
Therefore, GCD of numbers 278, 683, 205, 810 is 1
Given Input Data is 278, 683, 205, 810
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 278 is 2 x 139
Prime Factorization of 683 is 683
Prime Factorization of 205 is 5 x 41
Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5
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(278, 683) = 189874
GCD(278, 683) = ( 278 x 683 ) / 189874
GCD(278, 683) = 189874 / 189874
GCD(278, 683) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 205
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
GCD(1, 205) = 205 / 205
GCD(1, 205) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 810
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
GCD(1, 810) = 810 / 810
GCD(1, 810) = 1
GCD of 278, 683, 205, 810 is 1
