Greatest Common Divisior
We found the divisors of 638, 191, 69, 658 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 638, 191, 69, 658 is 1.
Therefore, GCD of numbers 638, 191, 69, 658 is 1
Given Input Data is 638, 191, 69, 658
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 638 is 2 x 11 x 29
Prime Factorization of 191 is 191
Prime Factorization of 69 is 3 x 23
Prime Factorization of 658 is 2 x 7 x 47
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(638, 191) = 121858
GCD(638, 191) = ( 638 x 191 ) / 121858
GCD(638, 191) = 121858 / 121858
GCD(638, 191) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 69
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
GCD(1, 69) = 69 / 69
GCD(1, 69) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 658
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
GCD(1, 658) = 658 / 658
GCD(1, 658) = 1
GCD of 638, 191, 69, 658 is 1
