We found the divisors of 919, 434, 423, 255 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 919, 434, 423, 255 is 1.

Therefore, GCD of numbers 919, 434, 423, 255 is 1

Given Input Data is 919, 434, 423, 255

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

Prime Factorization of 919 is 919

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 423 is 3 x 3 x 47

Prime Factorization of 255 is 3 x 5 x 17

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(919, 434) = 398846

GCD(919, 434) = ( 919 x 434 ) / 398846

GCD(919, 434) = 398846 / 398846

GCD(919, 434) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 423

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

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

GCD(1, 423) = 423 / 423

GCD(1, 423) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 255

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

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

GCD(1, 255) = 255 / 255

GCD(1, 255) = 1

GCD of 919, 434, 423, 255 is 1
