1, 11, 59, 649
Greatest Common Divisior
We found the divisors of 549, 574, 395, 649 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 549, 574, 395, 649 is 1.
Therefore, GCD of numbers 549, 574, 395, 649 is 1
Given Input Data is 549, 574, 395, 649
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 549 is 3 x 3 x 61
Prime Factorization of 574 is 2 x 7 x 41
Prime Factorization of 395 is 5 x 79
Prime Factorization of 649 is 11 x 59
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(549, 574) = 315126
GCD(549, 574) = ( 549 x 574 ) / 315126
GCD(549, 574) = 315126 / 315126
GCD(549, 574) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 395
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
GCD(1, 395) = 395 / 395
GCD(1, 395) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 649
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
GCD(1, 649) = 649 / 649
GCD(1, 649) = 1
GCD of 549, 574, 395, 649 is 1
