Greatest Common Divisior
We found the divisors of 669, 272, 809, 161 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 669, 272, 809, 161 is 1.
Therefore, GCD of numbers 669, 272, 809, 161 is 1
Given Input Data is 669, 272, 809, 161
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 669 is 3 x 223
Prime Factorization of 272 is 2 x 2 x 2 x 2 x 17
Prime Factorization of 809 is 809
Prime Factorization of 161 is 7 x 23
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(669, 272) = 181968
GCD(669, 272) = ( 669 x 272 ) / 181968
GCD(669, 272) = 181968 / 181968
GCD(669, 272) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 809
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
GCD(1, 809) = 809 / 809
GCD(1, 809) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 161
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
GCD(1, 161) = 161 / 161
GCD(1, 161) = 1
GCD of 669, 272, 809, 161 is 1
