Greatest Common Divisior
We found the divisors of 128, 785, 79, 191 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 128, 785, 79, 191 is 1.
Therefore, GCD of numbers 128, 785, 79, 191 is 1
Given Input Data is 128, 785, 79, 191
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 785 is 5 x 157
Prime Factorization of 79 is 79
Prime Factorization of 191 is 191
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(128, 785) = 100480
GCD(128, 785) = ( 128 x 785 ) / 100480
GCD(128, 785) = 100480 / 100480
GCD(128, 785) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
GCD(1, 79) = 79 / 79
GCD(1, 79) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 191
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 191) = 191
GCD(1, 191) = ( 1 x 191 ) / 191
GCD(1, 191) = 191 / 191
GCD(1, 191) = 1
GCD of 128, 785, 79, 191 is 1
