Greatest Common Divisior
We found the divisors of 173, 549, 849, 644 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 173, 549, 849, 644 is 1.
Therefore, GCD of numbers 173, 549, 849, 644 is 1
Given Input Data is 173, 549, 849, 644
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 173 is 173
Prime Factorization of 549 is 3 x 3 x 61
Prime Factorization of 849 is 3 x 283
Prime Factorization of 644 is 2 x 2 x 7 x 23
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, 549) = 94977
GCD(173, 549) = ( 173 x 549 ) / 94977
GCD(173, 549) = 94977 / 94977
GCD(173, 549) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 849
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
GCD(1, 849) = 849 / 849
GCD(1, 849) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 644
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
GCD(1, 644) = 644 / 644
GCD(1, 644) = 1
GCD of 173, 549, 849, 644 is 1
