1, 11, 79, 869
Greatest Common Divisior
We found the divisors of 394, 905, 27, 869 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 394, 905, 27, 869 is 1.
Therefore, GCD of numbers 394, 905, 27, 869 is 1
Given Input Data is 394, 905, 27, 869
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 394 is 2 x 197
Prime Factorization of 905 is 5 x 181
Prime Factorization of 27 is 3 x 3 x 3
Prime Factorization of 869 is 11 x 79
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(394, 905) = 356570
GCD(394, 905) = ( 394 x 905 ) / 356570
GCD(394, 905) = 356570 / 356570
GCD(394, 905) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 27
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 27) = 27
GCD(1, 27) = ( 1 x 27 ) / 27
GCD(1, 27) = 27 / 27
GCD(1, 27) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 869
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
GCD(1, 869) = 869 / 869
GCD(1, 869) = 1
GCD of 394, 905, 27, 869 is 1
