Greatest Common Divisior
We found the divisors of 168, 832, 720, 161 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 168, 832, 720, 161 is 1.
Therefore, GCD of numbers 168, 832, 720, 161 is 1
Given Input Data is 168, 832, 720, 161
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7
Prime Factorization of 832 is 2 x 2 x 2 x 2 x 2 x 2 x 13
Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5
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(168, 832) = 17472
GCD(168, 832) = ( 168 x 832 ) / 17472
GCD(168, 832) = 139776 / 17472
GCD(168, 832) = 8
Step2:
Here we consider the GCD from the above i.e. 8 as first number and the next as 720
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(8, 720) = 720
GCD(8, 720) = ( 8 x 720 ) / 720
GCD(8, 720) = 5760 / 720
GCD(8, 720) = 8
Step3:
Here we consider the GCD from the above i.e. 8 as first number and the next as 161
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(8, 161) = 1288
GCD(8, 161) = ( 8 x 161 ) / 1288
GCD(8, 161) = 1288 / 1288
GCD(8, 161) = 1
GCD of 168, 832, 720, 161 is 1
