We found the divisors of 511, 505, 30, 190 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 511, 505, 30, 190 is 1.

Therefore, GCD of numbers 511, 505, 30, 190 is 1

Given Input Data is 511, 505, 30, 190

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 505 is 5 x 101

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 190 is 2 x 5 x 19

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(511, 505) = 258055

GCD(511, 505) = ( 511 x 505 ) / 258055

GCD(511, 505) = 258055 / 258055

GCD(511, 505) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 190

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

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

GCD(1, 190) = 190 / 190

GCD(1, 190) = 1

GCD of 511, 505, 30, 190 is 1
