Greatest Common Divisior
We found the divisors of 812, 671, 656, 308 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 812, 671, 656, 308 is 1.
Therefore, GCD of numbers 812, 671, 656, 308 is 1
Given Input Data is 812, 671, 656, 308
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 812 is 2 x 2 x 7 x 29
Prime Factorization of 671 is 11 x 61
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 308 is 2 x 2 x 7 x 11
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(812, 671) = 544852
GCD(812, 671) = ( 812 x 671 ) / 544852
GCD(812, 671) = 544852 / 544852
GCD(812, 671) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 656
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
GCD(1, 656) = 656 / 656
GCD(1, 656) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 308
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
GCD(1, 308) = 308 / 308
GCD(1, 308) = 1
GCD of 812, 671, 656, 308 is 1
