Greatest Common Divisior
We found the divisors of 813, 388, 69 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 813, 388, 69 is 1.
Therefore, GCD of numbers 813, 388, 69 is 1
Given Input Data is 813, 388, 69
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 813 is 3 x 271
Prime Factorization of 388 is 2 x 2 x 97
Prime Factorization of 69 is 3 x 23
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, 388) = 315444
GCD(813, 388) = ( 813 x 388 ) / 315444
GCD(813, 388) = 315444 / 315444
GCD(813, 388) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 69
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
GCD(1, 69) = 69 / 69
GCD(1, 69) = 1
GCD of 813, 388, 69 is 1
