Make use of GCD Calculator to determine the Greatest Common Divisor of 206, 640, 11, 806 i.e. 1 largest integer that divides all the numbers equally.
GCD of 206, 640, 11, 806 is 1
GCD(206, 640, 11, 806) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 206, 640, 11, 806 is 1
GCD(206, 640, 11, 806) = 1
Given Input numbers are 206, 640, 11, 806
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 206

1, 11
Divisors of 806
List of positive integer divisors of 806 that divides 806 without a remainder.
1, 2, 13, 26, 31, 62, 403, 806
Greatest Common Divisior
We found the divisors of 206, 640, 11, 806 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 206, 640, 11, 806 is 1.
Therefore, GCD of numbers 206, 640, 11, 806 is 1
Given Input Data is 206, 640, 11, 806
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 206 is 2 x 103
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime Factorization of 11 is 11
Prime Factorization of 806 is 2 x 13 x 31
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(206, 640) = 65920
GCD(206, 640) = ( 206 x 640 ) / 65920
GCD(206, 640) = 131840 / 65920
GCD(206, 640) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 11
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 11) = 22
GCD(2, 11) = ( 2 x 11 ) / 22
GCD(2, 11) = 22 / 22
GCD(2, 11) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 806
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
GCD(1, 806) = 806 / 806
GCD(1, 806) = 1
GCD of 206, 640, 11, 806 is 1
