Greatest Common Divisior
We found the divisors of 646, 798, 207, 256 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 646, 798, 207, 256 is 1.
Therefore, GCD of numbers 646, 798, 207, 256 is 1
Given Input Data is 646, 798, 207, 256
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 798 is 2 x 3 x 7 x 19
Prime Factorization of 207 is 3 x 3 x 23
Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
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(646, 798) = 13566
GCD(646, 798) = ( 646 x 798 ) / 13566
GCD(646, 798) = 515508 / 13566
GCD(646, 798) = 38
Step2:
Here we consider the GCD from the above i.e. 38 as first number and the next as 207
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(38, 207) = 7866
GCD(38, 207) = ( 38 x 207 ) / 7866
GCD(38, 207) = 7866 / 7866
GCD(38, 207) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 256
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
GCD(1, 256) = 256 / 256
GCD(1, 256) = 1
GCD of 646, 798, 207, 256 is 1
