Greatest Common Divisior
We found the divisors of 554, 449, 57, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 554, 449, 57, 646 is 1.
Therefore, GCD of numbers 554, 449, 57, 646 is 1
Given Input Data is 554, 449, 57, 646
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 554 is 2 x 277
Prime Factorization of 449 is 449
Prime Factorization of 57 is 3 x 19
Prime Factorization of 646 is 2 x 17 x 19
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(554, 449) = 248746
GCD(554, 449) = ( 554 x 449 ) / 248746
GCD(554, 449) = 248746 / 248746
GCD(554, 449) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 57
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
GCD(1, 57) = 57 / 57
GCD(1, 57) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
GCD(1, 646) = 646 / 646
GCD(1, 646) = 1
GCD of 554, 449, 57, 646 is 1
