So the Greatest Common Divisior 215, 515, 676, 865 is 1.

Therefore, GCD of numbers 215, 515, 676, 865 is 1

Given Input Data is 215, 515, 676, 865

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 515 is 5 x 103

Prime Factorization of 676 is 2 x 2 x 13 x 13

Prime Factorization of 865 is 5 x 173

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(215, 515) = 22145

GCD(215, 515) = ( 215 x 515 ) / 22145

GCD(215, 515) = 110725 / 22145

GCD(215, 515) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 676

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

LCM(5, 676) = 3380

GCD(5, 676) = ( 5 x 676 ) / 3380

GCD(5, 676) = 3380 / 3380

GCD(5, 676) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 865

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

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

GCD(1, 865) = 865 / 865

GCD(1, 865) = 1

GCD of 215, 515, 676, 865 is 1
