Make use of GCD Calculator to determine the Greatest Common Divisor of 211, 393, 605 i.e. 1 largest integer that divides all the numbers equally.
GCD of 211, 393, 605 is 1
GCD(211, 393, 605) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 211, 393, 605 is 1
GCD(211, 393, 605) = 1
Given Input numbers are 211, 393, 605
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 211

1, 3, 131, 393
Divisors of 605
List of positive integer divisors of 605 that divides 605 without a remainder.
1, 5, 11, 55, 121, 605
Greatest Common Divisior
We found the divisors of 211, 393, 605 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 211, 393, 605 is 1.
Therefore, GCD of numbers 211, 393, 605 is 1
Given Input Data is 211, 393, 605
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 211 is 211
Prime Factorization of 393 is 3 x 131
Prime Factorization of 605 is 5 x 11 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(211, 393) = 82923
GCD(211, 393) = ( 211 x 393 ) / 82923
GCD(211, 393) = 82923 / 82923
GCD(211, 393) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 605
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
GCD(1, 605) = 605 / 605
GCD(1, 605) = 1
GCD of 211, 393, 605 is 1
