Greatest Common Divisior
We found the divisors of 279, 592, 405, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 279, 592, 405, 645 is 1.
Therefore, GCD of numbers 279, 592, 405, 645 is 1
Given Input Data is 279, 592, 405, 645
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 279 is 3 x 3 x 31
Prime Factorization of 592 is 2 x 2 x 2 x 2 x 37
Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5
Prime Factorization of 645 is 3 x 5 x 43
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(279, 592) = 165168
GCD(279, 592) = ( 279 x 592 ) / 165168
GCD(279, 592) = 165168 / 165168
GCD(279, 592) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 405
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
GCD(1, 405) = 405 / 405
GCD(1, 405) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 645
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
GCD(1, 645) = 645 / 645
GCD(1, 645) = 1
GCD of 279, 592, 405, 645 is 1
