We found the divisors of 831, 340, 42, 837 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 831, 340, 42, 837 is 1.

Therefore, GCD of numbers 831, 340, 42, 837 is 1

Given Input Data is 831, 340, 42, 837

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

Prime Factorization of 831 is 3 x 277

Prime Factorization of 340 is 2 x 2 x 5 x 17

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 837 is 3 x 3 x 3 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(831, 340) = 282540

GCD(831, 340) = ( 831 x 340 ) / 282540

GCD(831, 340) = 282540 / 282540

GCD(831, 340) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 42

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

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

GCD(1, 42) = 42 / 42

GCD(1, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 837

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

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

GCD(1, 837) = 837 / 837

GCD(1, 837) = 1

GCD of 831, 340, 42, 837 is 1
