Greatest Common Divisior
We found the divisors of 205, 556, 808, 290 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 205, 556, 808, 290 is 1.
Therefore, GCD of numbers 205, 556, 808, 290 is 1
Given Input Data is 205, 556, 808, 290
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 205 is 5 x 41
Prime Factorization of 556 is 2 x 2 x 139
Prime Factorization of 808 is 2 x 2 x 2 x 101
Prime Factorization of 290 is 2 x 5 x 29
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(205, 556) = 113980
GCD(205, 556) = ( 205 x 556 ) / 113980
GCD(205, 556) = 113980 / 113980
GCD(205, 556) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 808
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 808) = 808
GCD(1, 808) = ( 1 x 808 ) / 808
GCD(1, 808) = 808 / 808
GCD(1, 808) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 290
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 290) = 290
GCD(1, 290) = ( 1 x 290 ) / 290
GCD(1, 290) = 290 / 290
GCD(1, 290) = 1
GCD of 205, 556, 808, 290 is 1
