1, 31, 961
Greatest Common Divisior
We found the divisors of 728, 665, 961 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 728, 665, 961 is 1.
Therefore, GCD of numbers 728, 665, 961 is 1
Given Input Data is 728, 665, 961
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13
Prime Factorization of 665 is 5 x 7 x 19
Prime Factorization of 961 is 31 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(728, 665) = 69160
GCD(728, 665) = ( 728 x 665 ) / 69160
GCD(728, 665) = 484120 / 69160
GCD(728, 665) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 961
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 961) = 6727
GCD(7, 961) = ( 7 x 961 ) / 6727
GCD(7, 961) = 6727 / 6727
GCD(7, 961) = 1
GCD of 728, 665, 961 is 1
