Greatest Common Divisior
We found the divisors of 491, 809, 80, 798 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 491, 809, 80, 798 is 1.
Therefore, GCD of numbers 491, 809, 80, 798 is 1
Given Input Data is 491, 809, 80, 798
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 491 is 491
Prime Factorization of 809 is 809
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 798 is 2 x 3 x 7 x 19
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(491, 809) = 397219
GCD(491, 809) = ( 491 x 809 ) / 397219
GCD(491, 809) = 397219 / 397219
GCD(491, 809) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
GCD(1, 80) = 80 / 80
GCD(1, 80) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 798
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
GCD(1, 798) = 798 / 798
GCD(1, 798) = 1
GCD of 491, 809, 80, 798 is 1
