Greatest Common Divisior
We found the divisors of 422, 856, 684 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 422, 856, 684 is 2.
Therefore, GCD of numbers 422, 856, 684 is 2
Given Input Data is 422, 856, 684
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 422 is 2 x 211
Prime Factorization of 856 is 2 x 2 x 2 x 107
Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19
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(422, 856) = 180616
GCD(422, 856) = ( 422 x 856 ) / 180616
GCD(422, 856) = 361232 / 180616
GCD(422, 856) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 684
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 684) = 684
GCD(2, 684) = ( 2 x 684 ) / 684
GCD(2, 684) = 1368 / 684
GCD(2, 684) = 2
GCD of 422, 856, 684 is 2
