Greatest Common Divisior
We found the divisors of 479, 449, 645, 670 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 479, 449, 645, 670 is 1.
Therefore, GCD of numbers 479, 449, 645, 670 is 1
Given Input Data is 479, 449, 645, 670
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 479 is 479
Prime Factorization of 449 is 449
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 670 is 2 x 5 x 67
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(479, 449) = 215071
GCD(479, 449) = ( 479 x 449 ) / 215071
GCD(479, 449) = 215071 / 215071
GCD(479, 449) = 1
Step2:
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
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 670
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
GCD(1, 670) = 670 / 670
GCD(1, 670) = 1
GCD of 479, 449, 645, 670 is 1
