Greatest Common Divisior
We found the divisors of 939, 915, 688 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 939, 915, 688 is 1.
Therefore, GCD of numbers 939, 915, 688 is 1
Given Input Data is 939, 915, 688
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 939 is 3 x 313
Prime Factorization of 915 is 3 x 5 x 61
Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43
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(939, 915) = 286395
GCD(939, 915) = ( 939 x 915 ) / 286395
GCD(939, 915) = 859185 / 286395
GCD(939, 915) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 688
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 688) = 2064
GCD(3, 688) = ( 3 x 688 ) / 2064
GCD(3, 688) = 2064 / 2064
GCD(3, 688) = 1
GCD of 939, 915, 688 is 1
