Greatest Common Divisior
We found the divisors of 638, 369, 825 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 638, 369, 825 is 1.
Therefore, GCD of numbers 638, 369, 825 is 1
Given Input Data is 638, 369, 825
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 638 is 2 x 11 x 29
Prime Factorization of 369 is 3 x 3 x 41
Prime Factorization of 825 is 3 x 5 x 5 x 11
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(638, 369) = 235422
GCD(638, 369) = ( 638 x 369 ) / 235422
GCD(638, 369) = 235422 / 235422
GCD(638, 369) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 825
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 825) = 825
GCD(1, 825) = ( 1 x 825 ) / 825
GCD(1, 825) = 825 / 825
GCD(1, 825) = 1
GCD of 638, 369, 825 is 1
