We found the divisors of 217, 219, 245, 556 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 217, 219, 245, 556 is 1.

Therefore, GCD of numbers 217, 219, 245, 556 is 1

Given Input Data is 217, 219, 245, 556

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

Prime Factorization of 217 is 7 x 31

Prime Factorization of 219 is 3 x 73

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 556 is 2 x 2 x 139

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(217, 219) = 47523

GCD(217, 219) = ( 217 x 219 ) / 47523

GCD(217, 219) = 47523 / 47523

GCD(217, 219) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 556

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

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

GCD(1, 556) = 556 / 556

GCD(1, 556) = 1

GCD of 217, 219, 245, 556 is 1
