Make use of GCD Calculator to determine the Greatest Common Divisor of 809, 279, 30, 691 i.e. 1 largest integer that divides all the numbers equally.
GCD of 809, 279, 30, 691 is 1
GCD(809, 279, 30, 691) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 809, 279, 30, 691 is 1
GCD(809, 279, 30, 691) = 1
Given Input numbers are 809, 279, 30, 691
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 809

1, 691
Greatest Common Divisior
We found the divisors of 809, 279, 30, 691 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 809, 279, 30, 691 is 1.
Therefore, GCD of numbers 809, 279, 30, 691 is 1
Given Input Data is 809, 279, 30, 691
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 809 is 809
Prime Factorization of 279 is 3 x 3 x 31
Prime Factorization of 30 is 2 x 3 x 5
Prime Factorization of 691 is 691
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(809, 279) = 225711
GCD(809, 279) = ( 809 x 279 ) / 225711
GCD(809, 279) = 225711 / 225711
GCD(809, 279) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 30
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 30) = 30
GCD(1, 30) = ( 1 x 30 ) / 30
GCD(1, 30) = 30 / 30
GCD(1, 30) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 691
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
GCD(1, 691) = 691 / 691
GCD(1, 691) = 1
GCD of 809, 279, 30, 691 is 1
