Greatest Common Divisior

We found the divisors of 622, 611, 621, 261 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 622, 611, 621, 261 is 1.

Therefore, GCD of numbers 622, 611, 621, 261 is 1

Given Input Data is 622, 611, 621, 261

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

Prime Factorization of 622 is 2 x 311

Prime Factorization of 611 is 13 x 47

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 261 is 3 x 3 x 29

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(622, 611) = 380042

GCD(622, 611) = ( 622 x 611 ) / 380042

GCD(622, 611) = 380042 / 380042

GCD(622, 611) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

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

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

GCD of 622, 611, 621, 261 is 1
