1, 859
Greatest Common Divisior
We found the divisors of 686, 656, 859 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 686, 656, 859 is 1.
Therefore, GCD of numbers 686, 656, 859 is 1
Given Input Data is 686, 656, 859
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 686 is 2 x 7 x 7 x 7
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 859 is 859
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(686, 656) = 225008
GCD(686, 656) = ( 686 x 656 ) / 225008
GCD(686, 656) = 450016 / 225008
GCD(686, 656) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 859
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 859) = 1718
GCD(2, 859) = ( 2 x 859 ) / 1718
GCD(2, 859) = 1718 / 1718
GCD(2, 859) = 1
GCD of 686, 656, 859 is 1
