We found the divisors of 622, 255, 361, 455 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 622, 255, 361, 455 is 1.

Therefore, GCD of numbers 622, 255, 361, 455 is 1

Given Input Data is 622, 255, 361, 455

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

Prime Factorization of 622 is 2 x 311

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 361 is 19 x 19

Prime Factorization of 455 is 5 x 7 x 13

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, 255) = 158610

GCD(622, 255) = ( 622 x 255 ) / 158610

GCD(622, 255) = 158610 / 158610

GCD(622, 255) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 361

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

LCM(1, 361) = 361

GCD(1, 361) = ( 1 x 361 ) / 361

GCD(1, 361) = 361 / 361

GCD(1, 361) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 455

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

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

GCD(1, 455) = 455 / 455

GCD(1, 455) = 1

GCD of 622, 255, 361, 455 is 1
