We found the divisors of 911, 680, 12, 782 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 911, 680, 12, 782 is 1.

Therefore, GCD of numbers 911, 680, 12, 782 is 1

Given Input Data is 911, 680, 12, 782

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 911 is 911

Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 782 is 2 x 17 x 23

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(911, 680) = 619480

GCD(911, 680) = ( 911 x 680 ) / 619480

GCD(911, 680) = 619480 / 619480

GCD(911, 680) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 12

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

GCD(1, 12) = 12 / 12

GCD(1, 12) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 782

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

GCD(1, 782) = 782 / 782

GCD(1, 782) = 1

GCD of 911, 680, 12, 782 is 1
