Greatest Common Divisior
We found the divisors of 489, 223, 81, 858 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 489, 223, 81, 858 is 1.
Therefore, GCD of numbers 489, 223, 81, 858 is 1
Given Input Data is 489, 223, 81, 858
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 489 is 3 x 163
Prime Factorization of 223 is 223
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 858 is 2 x 3 x 11 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(489, 223) = 109047
GCD(489, 223) = ( 489 x 223 ) / 109047
GCD(489, 223) = 109047 / 109047
GCD(489, 223) = 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 858
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
GCD(1, 858) = 858 / 858
GCD(1, 858) = 1
GCD of 489, 223, 81, 858 is 1
