Greatest Common Divisior
We found the divisors of 129, 178, 805, 371 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 129, 178, 805, 371 is 1.
Therefore, GCD of numbers 129, 178, 805, 371 is 1
Given Input Data is 129, 178, 805, 371
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 129 is 3 x 43
Prime Factorization of 178 is 2 x 89
Prime Factorization of 805 is 5 x 7 x 23
Prime Factorization of 371 is 7 x 53
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, 178) = 22962
GCD(129, 178) = ( 129 x 178 ) / 22962
GCD(129, 178) = 22962 / 22962
GCD(129, 178) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 805
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
GCD(1, 805) = 805 / 805
GCD(1, 805) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 371
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 371) = 371
GCD(1, 371) = ( 1 x 371 ) / 371
GCD(1, 371) = 371 / 371
GCD(1, 371) = 1
GCD of 129, 178, 805, 371 is 1
