We found the divisors of 190, 439, 772, 255 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 190, 439, 772, 255 is 1.

Therefore, GCD of numbers 190, 439, 772, 255 is 1

Given Input Data is 190, 439, 772, 255

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

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 439 is 439

Prime Factorization of 772 is 2 x 2 x 193

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(190, 439) = 83410

GCD(190, 439) = ( 190 x 439 ) / 83410

GCD(190, 439) = 83410 / 83410

GCD(190, 439) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 772

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

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

GCD(1, 772) = 772 / 772

GCD(1, 772) = 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 190, 439, 772, 255 is 1
