Greatest Common Divisior
We found the divisors of 161, 981, 68, 605 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 161, 981, 68, 605 is 1.
Therefore, GCD of numbers 161, 981, 68, 605 is 1
Given Input Data is 161, 981, 68, 605
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 161 is 7 x 23
Prime Factorization of 981 is 3 x 3 x 109
Prime Factorization of 68 is 2 x 2 x 17
Prime Factorization of 605 is 5 x 11 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(161, 981) = 157941
GCD(161, 981) = ( 161 x 981 ) / 157941
GCD(161, 981) = 157941 / 157941
GCD(161, 981) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 68
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
GCD(1, 68) = 68 / 68
GCD(1, 68) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 605
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
GCD(1, 605) = 605 / 605
GCD(1, 605) = 1
GCD of 161, 981, 68, 605 is 1
