Greatest Common Divisior
We found the divisors of 727, 861, 85, 491 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 727, 861, 85, 491 is 1.
Therefore, GCD of numbers 727, 861, 85, 491 is 1
Given Input Data is 727, 861, 85, 491
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 727 is 727
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 85 is 5 x 17
Prime Factorization of 491 is 491
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(727, 861) = 625947
GCD(727, 861) = ( 727 x 861 ) / 625947
GCD(727, 861) = 625947 / 625947
GCD(727, 861) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 85
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 85) = 85
GCD(1, 85) = ( 1 x 85 ) / 85
GCD(1, 85) = 85 / 85
GCD(1, 85) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 491
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
GCD(1, 491) = 491 / 491
GCD(1, 491) = 1
GCD of 727, 861, 85, 491 is 1
