We found the divisors of 221, 515, 26, 860 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 221, 515, 26, 860 is 1.

Therefore, GCD of numbers 221, 515, 26, 860 is 1

Given Input Data is 221, 515, 26, 860

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 515 is 5 x 103

Prime Factorization of 26 is 2 x 13

Prime Factorization of 860 is 2 x 2 x 5 x 43

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(221, 515) = 113815

GCD(221, 515) = ( 221 x 515 ) / 113815

GCD(221, 515) = 113815 / 113815

GCD(221, 515) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 26

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

LCM(1, 26) = 26

GCD(1, 26) = ( 1 x 26 ) / 26

GCD(1, 26) = 26 / 26

GCD(1, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 860

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

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

GCD(1, 860) = 860 / 860

GCD(1, 860) = 1

GCD of 221, 515, 26, 860 is 1
