Greatest Common Divisior
We found the divisors of 215, 290, 905, 729 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 290, 905, 729 is 1.
Therefore, GCD of numbers 215, 290, 905, 729 is 1
Given Input Data is 215, 290, 905, 729
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 215 is 5 x 43
Prime Factorization of 290 is 2 x 5 x 29
Prime Factorization of 905 is 5 x 181
Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3
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(215, 290) = 12470
GCD(215, 290) = ( 215 x 290 ) / 12470
GCD(215, 290) = 62350 / 12470
GCD(215, 290) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 905
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 905) = 905
GCD(5, 905) = ( 5 x 905 ) / 905
GCD(5, 905) = 4525 / 905
GCD(5, 905) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 729
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 729) = 3645
GCD(5, 729) = ( 5 x 729 ) / 3645
GCD(5, 729) = 3645 / 3645
GCD(5, 729) = 1
GCD of 215, 290, 905, 729 is 1
