Greatest Common Divisior
We found the divisors of 217, 655, 27, 845 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 217, 655, 27, 845 is 1.
Therefore, GCD of numbers 217, 655, 27, 845 is 1
Given Input Data is 217, 655, 27, 845
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 217 is 7 x 31
Prime Factorization of 655 is 5 x 131
Prime Factorization of 27 is 3 x 3 x 3
Prime Factorization of 845 is 5 x 13 x 13
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(217, 655) = 142135
GCD(217, 655) = ( 217 x 655 ) / 142135
GCD(217, 655) = 142135 / 142135
GCD(217, 655) = 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 845
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
GCD(1, 845) = 845 / 845
GCD(1, 845) = 1
GCD of 217, 655, 27, 845 is 1
