Greatest Common Divisior
We found the divisors of 428, 834, 173, 939 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 428, 834, 173, 939 is 1.
Therefore, GCD of numbers 428, 834, 173, 939 is 1
Given Input Data is 428, 834, 173, 939
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 428 is 2 x 2 x 107
Prime Factorization of 834 is 2 x 3 x 139
Prime Factorization of 173 is 173
Prime Factorization of 939 is 3 x 313
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(428, 834) = 178476
GCD(428, 834) = ( 428 x 834 ) / 178476
GCD(428, 834) = 356952 / 178476
GCD(428, 834) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 173
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 173) = 346
GCD(2, 173) = ( 2 x 173 ) / 346
GCD(2, 173) = 346 / 346
GCD(2, 173) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 939
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
GCD(1, 939) = 939 / 939
GCD(1, 939) = 1
GCD of 428, 834, 173, 939 is 1
