We found the divisors of 835, 707, 78, 830 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 835, 707, 78, 830 is 1.

Therefore, GCD of numbers 835, 707, 78, 830 is 1

Given Input Data is 835, 707, 78, 830

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

Prime Factorization of 835 is 5 x 167

Prime Factorization of 707 is 7 x 101

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 830 is 2 x 5 x 83

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(835, 707) = 590345

GCD(835, 707) = ( 835 x 707 ) / 590345

GCD(835, 707) = 590345 / 590345

GCD(835, 707) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 830

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

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

GCD(1, 830) = 830 / 830

GCD(1, 830) = 1

GCD of 835, 707, 78, 830 is 1
