Greatest Common Divisior
We found the divisors of 988, 813, 669, 398 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 988, 813, 669, 398 is 1.
Therefore, GCD of numbers 988, 813, 669, 398 is 1
Given Input Data is 988, 813, 669, 398
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 988 is 2 x 2 x 13 x 19
Prime Factorization of 813 is 3 x 271
Prime Factorization of 669 is 3 x 223
Prime Factorization of 398 is 2 x 199
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(988, 813) = 803244
GCD(988, 813) = ( 988 x 813 ) / 803244
GCD(988, 813) = 803244 / 803244
GCD(988, 813) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 669
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
GCD(1, 669) = 669 / 669
GCD(1, 669) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 398
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
GCD(1, 398) = 398 / 398
GCD(1, 398) = 1
GCD of 988, 813, 669, 398 is 1
