1, 769

Greatest Common Divisior

We found the divisors of 830, 831, 84, 769 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 830, 831, 84, 769 is 1.

Therefore, GCD of numbers 830, 831, 84, 769 is 1

Given Input Data is 830, 831, 84, 769

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

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 831 is 3 x 277

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 769 is 769

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(830, 831) = 689730

GCD(830, 831) = ( 830 x 831 ) / 689730

GCD(830, 831) = 689730 / 689730

GCD(830, 831) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 84

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

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

GCD(1, 84) = 84 / 84

GCD(1, 84) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 769

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

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

GCD(1, 769) = 769 / 769

GCD(1, 769) = 1

GCD of 830, 831, 84, 769 is 1
