Greatest Common Divisior
We found the divisors of 129, 392, 903, 930 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 129, 392, 903, 930 is 1.
Therefore, GCD of numbers 129, 392, 903, 930 is 1
Given Input Data is 129, 392, 903, 930
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 129 is 3 x 43
Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7
Prime Factorization of 903 is 3 x 7 x 43
Prime Factorization of 930 is 2 x 3 x 5 x 31
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(129, 392) = 50568
GCD(129, 392) = ( 129 x 392 ) / 50568
GCD(129, 392) = 50568 / 50568
GCD(129, 392) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 903
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
GCD(1, 903) = 903 / 903
GCD(1, 903) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 930
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 930) = 930
GCD(1, 930) = ( 1 x 930 ) / 930
GCD(1, 930) = 930 / 930
GCD(1, 930) = 1
GCD of 129, 392, 903, 930 is 1
