Greatest Common Divisior
We found the divisors of 215, 561, 797, 486 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 561, 797, 486 is 1.
Therefore, GCD of numbers 215, 561, 797, 486 is 1
Given Input Data is 215, 561, 797, 486
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 215 is 5 x 43
Prime Factorization of 561 is 3 x 11 x 17
Prime Factorization of 797 is 797
Prime Factorization of 486 is 2 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, 561) = 120615
GCD(215, 561) = ( 215 x 561 ) / 120615
GCD(215, 561) = 120615 / 120615
GCD(215, 561) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 797
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
GCD(1, 797) = 797 / 797
GCD(1, 797) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 486
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
GCD(1, 486) = 486 / 486
GCD(1, 486) = 1
GCD of 215, 561, 797, 486 is 1
