Greatest Common Divisior
We found the divisors of 656, 290, 173, 161 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 656, 290, 173, 161 is 1.
Therefore, GCD of numbers 656, 290, 173, 161 is 1
Given Input Data is 656, 290, 173, 161
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 290 is 2 x 5 x 29
Prime Factorization of 173 is 173
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(656, 290) = 95120
GCD(656, 290) = ( 656 x 290 ) / 95120
GCD(656, 290) = 190240 / 95120
GCD(656, 290) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 173
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 173) = 346
GCD(2, 173) = ( 2 x 173 ) / 346
GCD(2, 173) = 346 / 346
GCD(2, 173) = 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 656, 290, 173, 161 is 1
