Greatest Common Divisior
We found the divisors of 172, 797, 981 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 172, 797, 981 is 1.
Therefore, GCD of numbers 172, 797, 981 is 1
Given Input Data is 172, 797, 981
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 172 is 2 x 2 x 43
Prime Factorization of 797 is 797
Prime Factorization of 981 is 3 x 3 x 109
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(172, 797) = 137084
GCD(172, 797) = ( 172 x 797 ) / 137084
GCD(172, 797) = 137084 / 137084
GCD(172, 797) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 981
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
GCD(1, 981) = 981 / 981
GCD(1, 981) = 1
GCD of 172, 797, 981 is 1
