Make use of GCD Calculator to determine the Greatest Common Divisor of 395, 215, 691, 317 i.e. 1 largest integer that divides all the numbers equally.
GCD of 395, 215, 691, 317 is 1
GCD(395, 215, 691, 317) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 395, 215, 691, 317 is 1
GCD(395, 215, 691, 317) = 1
Given Input numbers are 395, 215, 691, 317
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 395, 215, 691, 317 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 395, 215, 691, 317 is 1.
Therefore, GCD of numbers 395, 215, 691, 317 is 1
Given Input Data is 395, 215, 691, 317
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 395 is 5 x 79
Prime Factorization of 215 is 5 x 43
Prime Factorization of 691 is 691
Prime Factorization of 317 is 317
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(395, 215) = 16985
GCD(395, 215) = ( 395 x 215 ) / 16985
GCD(395, 215) = 84925 / 16985
GCD(395, 215) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 691
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 691) = 3455
GCD(5, 691) = ( 5 x 691 ) / 3455
GCD(5, 691) = 3455 / 3455
GCD(5, 691) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 317
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 317) = 317
GCD(1, 317) = ( 1 x 317 ) / 317
GCD(1, 317) = 317 / 317
GCD(1, 317) = 1
GCD of 395, 215, 691, 317 is 1
