Make use of GCD Calculator to determine the Greatest Common Divisor of 813, 344, 20, 717 i.e. 1 largest integer that divides all the numbers equally.
GCD of 813, 344, 20, 717 is 1
GCD(813, 344, 20, 717) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 813, 344, 20, 717 is 1
GCD(813, 344, 20, 717) = 1
Given Input numbers are 813, 344, 20, 717
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 239, 717
Greatest Common Divisior
We found the divisors of 813, 344, 20, 717 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 813, 344, 20, 717 is 1.
Therefore, GCD of numbers 813, 344, 20, 717 is 1
Given Input Data is 813, 344, 20, 717
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 813 is 3 x 271
Prime Factorization of 344 is 2 x 2 x 2 x 43
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 717 is 3 x 239
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(813, 344) = 279672
GCD(813, 344) = ( 813 x 344 ) / 279672
GCD(813, 344) = 279672 / 279672
GCD(813, 344) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 717
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
GCD(1, 717) = 717 / 717
GCD(1, 717) = 1
GCD of 813, 344, 20, 717 is 1
