We found the divisors of 831, 443, 801, 690 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 831, 443, 801, 690 is 1.

Therefore, GCD of numbers 831, 443, 801, 690 is 1

Given Input Data is 831, 443, 801, 690

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

Prime Factorization of 831 is 3 x 277

Prime Factorization of 443 is 443

Prime Factorization of 801 is 3 x 3 x 89

Prime Factorization of 690 is 2 x 3 x 5 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(831, 443) = 368133

GCD(831, 443) = ( 831 x 443 ) / 368133

GCD(831, 443) = 368133 / 368133

GCD(831, 443) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 801

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

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

GCD(1, 801) = 801 / 801

GCD(1, 801) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 690

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

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

GCD(1, 690) = 690 / 690

GCD(1, 690) = 1

GCD of 831, 443, 801, 690 is 1
