1, 223
Greatest Common Divisior
We found the divisors of 398, 418, 604, 223 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 398, 418, 604, 223 is 1.
Therefore, GCD of numbers 398, 418, 604, 223 is 1
Given Input Data is 398, 418, 604, 223
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 398 is 2 x 199
Prime Factorization of 418 is 2 x 11 x 19
Prime Factorization of 604 is 2 x 2 x 151
Prime Factorization of 223 is 223
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(398, 418) = 83182
GCD(398, 418) = ( 398 x 418 ) / 83182
GCD(398, 418) = 166364 / 83182
GCD(398, 418) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 604
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 604) = 604
GCD(2, 604) = ( 2 x 604 ) / 604
GCD(2, 604) = 1208 / 604
GCD(2, 604) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 223
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 223) = 446
GCD(2, 223) = ( 2 x 223 ) / 446
GCD(2, 223) = 446 / 446
GCD(2, 223) = 1
GCD of 398, 418, 604, 223 is 1
