Greatest Common Divisior
We found the divisors of 998, 195, 419, 640 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 998, 195, 419, 640 is 1.
Therefore, GCD of numbers 998, 195, 419, 640 is 1
Given Input Data is 998, 195, 419, 640
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 998 is 2 x 499
Prime Factorization of 195 is 3 x 5 x 13
Prime Factorization of 419 is 419
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
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(998, 195) = 194610
GCD(998, 195) = ( 998 x 195 ) / 194610
GCD(998, 195) = 194610 / 194610
GCD(998, 195) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 419
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
GCD(1, 419) = 419 / 419
GCD(1, 419) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 640
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
GCD(1, 640) = 640 / 640
GCD(1, 640) = 1
GCD of 998, 195, 419, 640 is 1
