1, 139
Greatest Common Divisior
We found the divisors of 328, 138, 669, 139 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 328, 138, 669, 139 is 1.
Therefore, GCD of numbers 328, 138, 669, 139 is 1
Given Input Data is 328, 138, 669, 139
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 328 is 2 x 2 x 2 x 41
Prime Factorization of 138 is 2 x 3 x 23
Prime Factorization of 669 is 3 x 223
Prime Factorization of 139 is 139
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(328, 138) = 22632
GCD(328, 138) = ( 328 x 138 ) / 22632
GCD(328, 138) = 45264 / 22632
GCD(328, 138) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 669
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 669) = 1338
GCD(2, 669) = ( 2 x 669 ) / 1338
GCD(2, 669) = 1338 / 1338
GCD(2, 669) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 139
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
GCD(1, 139) = 139 / 139
GCD(1, 139) = 1
GCD of 328, 138, 669, 139 is 1
