Greatest Common Divisior
We found the divisors of 28, 858, 939, 342 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 28, 858, 939, 342 is 1.
Therefore, GCD of numbers 28, 858, 939, 342 is 1
Given Input Data is 28, 858, 939, 342
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 858 is 2 x 3 x 11 x 13
Prime Factorization of 939 is 3 x 313
Prime Factorization of 342 is 2 x 3 x 3 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(28, 858) = 12012
GCD(28, 858) = ( 28 x 858 ) / 12012
GCD(28, 858) = 24024 / 12012
GCD(28, 858) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 939
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 939) = 1878
GCD(2, 939) = ( 2 x 939 ) / 1878
GCD(2, 939) = 1878 / 1878
GCD(2, 939) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 342
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
GCD(1, 342) = 342 / 342
GCD(1, 342) = 1
GCD of 28, 858, 939, 342 is 1
