Greatest Common Divisior
We found the divisors of 28, 858, 308, 634 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 28, 858, 308, 634 is 2.
Therefore, GCD of numbers 28, 858, 308, 634 is 2
Given Input Data is 28, 858, 308, 634
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 308 is 2 x 2 x 7 x 11
Prime Factorization of 634 is 2 x 317
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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 308
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 308) = 308
GCD(2, 308) = ( 2 x 308 ) / 308
GCD(2, 308) = 616 / 308
GCD(2, 308) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 634
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 634) = 634
GCD(2, 634) = ( 2 x 634 ) / 634
GCD(2, 634) = 1268 / 634
GCD(2, 634) = 2
GCD of 28, 858, 308, 634 is 2
