Greatest Common Divisior
We found the divisors of 649, 638, 173, 244 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 649, 638, 173, 244 is 1.
Therefore, GCD of numbers 649, 638, 173, 244 is 1
Given Input Data is 649, 638, 173, 244
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 649 is 11 x 59
Prime Factorization of 638 is 2 x 11 x 29
Prime Factorization of 173 is 173
Prime Factorization of 244 is 2 x 2 x 61
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(649, 638) = 37642
GCD(649, 638) = ( 649 x 638 ) / 37642
GCD(649, 638) = 414062 / 37642
GCD(649, 638) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 173
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 173) = 1903
GCD(11, 173) = ( 11 x 173 ) / 1903
GCD(11, 173) = 1903 / 1903
GCD(11, 173) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 244
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
GCD(1, 244) = 244 / 244
GCD(1, 244) = 1
GCD of 649, 638, 173, 244 is 1
