Greatest Common Divisior
We found the divisors of 643, 231, 245, 294 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 231, 245, 294 is 1.
Therefore, GCD of numbers 643, 231, 245, 294 is 1
Given Input Data is 643, 231, 245, 294
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 231 is 3 x 7 x 11
Prime Factorization of 245 is 5 x 7 x 7
Prime Factorization of 294 is 2 x 3 x 7 x 7
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(643, 231) = 148533
GCD(643, 231) = ( 643 x 231 ) / 148533
GCD(643, 231) = 148533 / 148533
GCD(643, 231) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 245
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
GCD(1, 245) = 245 / 245
GCD(1, 245) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 294
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 294) = 294
GCD(1, 294) = ( 1 x 294 ) / 294
GCD(1, 294) = 294 / 294
GCD(1, 294) = 1
GCD of 643, 231, 245, 294 is 1
