Greatest Common Divisior
We found the divisors of 389, 721, 81, 468 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 389, 721, 81, 468 is 1.
Therefore, GCD of numbers 389, 721, 81, 468 is 1
Given Input Data is 389, 721, 81, 468
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 389 is 389
Prime Factorization of 721 is 7 x 103
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 468 is 2 x 2 x 3 x 3 x 13
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(389, 721) = 280469
GCD(389, 721) = ( 389 x 721 ) / 280469
GCD(389, 721) = 280469 / 280469
GCD(389, 721) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
GCD(1, 81) = 81 / 81
GCD(1, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 468
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 468) = 468
GCD(1, 468) = ( 1 x 468 ) / 468
GCD(1, 468) = 468 / 468
GCD(1, 468) = 1
GCD of 389, 721, 81, 468 is 1
