Greatest Common Divisior
We found the divisors of 173, 485, 26, 561 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 173, 485, 26, 561 is 1.
Therefore, GCD of numbers 173, 485, 26, 561 is 1
Given Input Data is 173, 485, 26, 561
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 173 is 173
Prime Factorization of 485 is 5 x 97
Prime Factorization of 26 is 2 x 13
Prime Factorization of 561 is 3 x 11 x 17
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(173, 485) = 83905
GCD(173, 485) = ( 173 x 485 ) / 83905
GCD(173, 485) = 83905 / 83905
GCD(173, 485) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 26
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 26) = 26
GCD(1, 26) = ( 1 x 26 ) / 26
GCD(1, 26) = 26 / 26
GCD(1, 26) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 561
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
GCD(1, 561) = 561 / 561
GCD(1, 561) = 1
GCD of 173, 485, 26, 561 is 1
