We found the divisors of 615, 207, 20, 833 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 615, 207, 20, 833 is 1.

Therefore, GCD of numbers 615, 207, 20, 833 is 1

Given Input Data is 615, 207, 20, 833

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 833 is 7 x 7 x 17

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(615, 207) = 42435

GCD(615, 207) = ( 615 x 207 ) / 42435

GCD(615, 207) = 127305 / 42435

GCD(615, 207) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 20

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

LCM(3, 20) = 60

GCD(3, 20) = ( 3 x 20 ) / 60

GCD(3, 20) = 60 / 60

GCD(3, 20) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 833

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

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

GCD(1, 833) = 833 / 833

GCD(1, 833) = 1

GCD of 615, 207, 20, 833 is 1
