1, 17, 23, 391
Greatest Common Divisior
We found the divisors of 729, 529, 891, 391 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 729, 529, 891, 391 is 1.
Therefore, GCD of numbers 729, 529, 891, 391 is 1
Given Input Data is 729, 529, 891, 391
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3
Prime Factorization of 529 is 23 x 23
Prime Factorization of 891 is 3 x 3 x 3 x 3 x 11
Prime Factorization of 391 is 17 x 23
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(729, 529) = 385641
GCD(729, 529) = ( 729 x 529 ) / 385641
GCD(729, 529) = 385641 / 385641
GCD(729, 529) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 891
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
GCD(1, 891) = 891 / 891
GCD(1, 891) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 391
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
GCD(1, 391) = 391 / 391
GCD(1, 391) = 1
GCD of 729, 529, 891, 391 is 1
