Make use of GCD Calculator to determine the Greatest Common Divisor of 831, 424, 11, 640 i.e. 1 largest integer that divides all the numbers equally.
GCD of 831, 424, 11, 640 is 1
GCD(831, 424, 11, 640) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 831, 424, 11, 640 is 1
GCD(831, 424, 11, 640) = 1
Given Input numbers are 831, 424, 11, 640
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 831

1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
Greatest Common Divisior
We found the divisors of 831, 424, 11, 640 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 831, 424, 11, 640 is 1.
Therefore, GCD of numbers 831, 424, 11, 640 is 1
Given Input Data is 831, 424, 11, 640
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 831 is 3 x 277
Prime Factorization of 424 is 2 x 2 x 2 x 53
Prime Factorization of 11 is 11
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
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(831, 424) = 352344
GCD(831, 424) = ( 831 x 424 ) / 352344
GCD(831, 424) = 352344 / 352344
GCD(831, 424) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 11
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 11) = 11
GCD(1, 11) = ( 1 x 11 ) / 11
GCD(1, 11) = 11 / 11
GCD(1, 11) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 640
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
GCD(1, 640) = 640 / 640
GCD(1, 640) = 1
GCD of 831, 424, 11, 640 is 1
