1, 3, 43, 129
Greatest Common Divisior
We found the divisors of 661, 923, 17, 129 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 661, 923, 17, 129 is 1.
Therefore, GCD of numbers 661, 923, 17, 129 is 1
Given Input Data is 661, 923, 17, 129
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 661 is 661
Prime Factorization of 923 is 13 x 71
Prime Factorization of 17 is 17
Prime Factorization of 129 is 3 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(661, 923) = 610103
GCD(661, 923) = ( 661 x 923 ) / 610103
GCD(661, 923) = 610103 / 610103
GCD(661, 923) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 17
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
GCD(1, 17) = 17 / 17
GCD(1, 17) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 129
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
GCD(1, 129) = 129 / 129
GCD(1, 129) = 1
GCD of 661, 923, 17, 129 is 1
