Greatest Common Divisior
We found the divisors of 644, 239, 555, 998 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 644, 239, 555, 998 is 1.
Therefore, GCD of numbers 644, 239, 555, 998 is 1
Given Input Data is 644, 239, 555, 998
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 644 is 2 x 2 x 7 x 23
Prime Factorization of 239 is 239
Prime Factorization of 555 is 3 x 5 x 37
Prime Factorization of 998 is 2 x 499
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(644, 239) = 153916
GCD(644, 239) = ( 644 x 239 ) / 153916
GCD(644, 239) = 153916 / 153916
GCD(644, 239) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 555
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
GCD(1, 555) = 555 / 555
GCD(1, 555) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 998
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 998) = 998
GCD(1, 998) = ( 1 x 998 ) / 998
GCD(1, 998) = 998 / 998
GCD(1, 998) = 1
GCD of 644, 239, 555, 998 is 1
