1, 3, 9, 61, 183, 549
Greatest Common Divisior
We found the divisors of 861, 930, 68, 549 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 861, 930, 68, 549 is 1.
Therefore, GCD of numbers 861, 930, 68, 549 is 1
Given Input Data is 861, 930, 68, 549
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 930 is 2 x 3 x 5 x 31
Prime Factorization of 68 is 2 x 2 x 17
Prime Factorization of 549 is 3 x 3 x 61
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(861, 930) = 266910
GCD(861, 930) = ( 861 x 930 ) / 266910
GCD(861, 930) = 800730 / 266910
GCD(861, 930) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 68
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 68) = 204
GCD(3, 68) = ( 3 x 68 ) / 204
GCD(3, 68) = 204 / 204
GCD(3, 68) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 549
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
GCD(1, 549) = 549 / 549
GCD(1, 549) = 1
GCD of 861, 930, 68, 549 is 1
