Greatest Common Divisior
We found the divisors of 641, 676, 485, 838 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 641, 676, 485, 838 is 1.
Therefore, GCD of numbers 641, 676, 485, 838 is 1
Given Input Data is 641, 676, 485, 838
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 641 is 641
Prime Factorization of 676 is 2 x 2 x 13 x 13
Prime Factorization of 485 is 5 x 97
Prime Factorization of 838 is 2 x 419
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(641, 676) = 433316
GCD(641, 676) = ( 641 x 676 ) / 433316
GCD(641, 676) = 433316 / 433316
GCD(641, 676) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 485
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
GCD(1, 485) = 485 / 485
GCD(1, 485) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 838
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
GCD(1, 838) = 838 / 838
GCD(1, 838) = 1
GCD of 641, 676, 485, 838 is 1
