Greatest Common Divisior
We found the divisors of 829, 785, 405, 634 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 829, 785, 405, 634 is 1.
Therefore, GCD of numbers 829, 785, 405, 634 is 1
Given Input Data is 829, 785, 405, 634
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 829 is 829
Prime Factorization of 785 is 5 x 157
Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5
Prime Factorization of 634 is 2 x 317
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(829, 785) = 650765
GCD(829, 785) = ( 829 x 785 ) / 650765
GCD(829, 785) = 650765 / 650765
GCD(829, 785) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 405
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
GCD(1, 405) = 405 / 405
GCD(1, 405) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 634
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
GCD(1, 634) = 634 / 634
GCD(1, 634) = 1
GCD of 829, 785, 405, 634 is 1
