Greatest Common Divisior
We found the divisors of 398, 991, 119, 990 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 398, 991, 119, 990 is 1.
Therefore, GCD of numbers 398, 991, 119, 990 is 1
Given Input Data is 398, 991, 119, 990
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 398 is 2 x 199
Prime Factorization of 991 is 991
Prime Factorization of 119 is 7 x 17
Prime Factorization of 990 is 2 x 3 x 3 x 5 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(398, 991) = 394418
GCD(398, 991) = ( 398 x 991 ) / 394418
GCD(398, 991) = 394418 / 394418
GCD(398, 991) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 119
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 119) = 119
GCD(1, 119) = ( 1 x 119 ) / 119
GCD(1, 119) = 119 / 119
GCD(1, 119) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 990
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
GCD(1, 990) = 990 / 990
GCD(1, 990) = 1
GCD of 398, 991, 119, 990 is 1
