Greatest Common Divisior
We found the divisors of 404, 978, 454, 640 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 404, 978, 454, 640 is 2.
Therefore, GCD of numbers 404, 978, 454, 640 is 2
Given Input Data is 404, 978, 454, 640
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 404 is 2 x 2 x 101
Prime Factorization of 978 is 2 x 3 x 163
Prime Factorization of 454 is 2 x 227
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(404, 978) = 197556
GCD(404, 978) = ( 404 x 978 ) / 197556
GCD(404, 978) = 395112 / 197556
GCD(404, 978) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 454
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 454) = 454
GCD(2, 454) = ( 2 x 454 ) / 454
GCD(2, 454) = 908 / 454
GCD(2, 454) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 640
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 640) = 640
GCD(2, 640) = ( 2 x 640 ) / 640
GCD(2, 640) = 1280 / 640
GCD(2, 640) = 2
GCD of 404, 978, 454, 640 is 2
