So the Greatest Common Divisior 615, 730, 831, 866 is 1.

Therefore, GCD of numbers 615, 730, 831, 866 is 1

Given Input Data is 615, 730, 831, 866

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 730 is 2 x 5 x 73

Prime Factorization of 831 is 3 x 277

Prime Factorization of 866 is 2 x 433

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, 730) = 89790

GCD(615, 730) = ( 615 x 730 ) / 89790

GCD(615, 730) = 448950 / 89790

GCD(615, 730) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 831

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

LCM(5, 831) = 4155

GCD(5, 831) = ( 5 x 831 ) / 4155

GCD(5, 831) = 4155 / 4155

GCD(5, 831) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 866

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

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

GCD(1, 866) = 866 / 866

GCD(1, 866) = 1

GCD of 615, 730, 831, 866 is 1
