We found the divisors of 833, 685, 31, 220 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 833, 685, 31, 220 is 1.

Therefore, GCD of numbers 833, 685, 31, 220 is 1

Given Input Data is 833, 685, 31, 220

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

Prime Factorization of 833 is 7 x 7 x 17

Prime Factorization of 685 is 5 x 137

Prime Factorization of 31 is 31

Prime Factorization of 220 is 2 x 2 x 5 x 11

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(833, 685) = 570605

GCD(833, 685) = ( 833 x 685 ) / 570605

GCD(833, 685) = 570605 / 570605

GCD(833, 685) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 31

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

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

GCD(1, 31) = 31 / 31

GCD(1, 31) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

GCD of 833, 685, 31, 220 is 1
