Greatest Common Divisior

We found the divisors of 311, 561, 711, 175 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 311, 561, 711, 175 is 1.

Therefore, GCD of numbers 311, 561, 711, 175 is 1

Given Input Data is 311, 561, 711, 175

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

Prime Factorization of 311 is 311

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 711 is 3 x 3 x 79

Prime Factorization of 175 is 5 x 5 x 7

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(311, 561) = 174471

GCD(311, 561) = ( 311 x 561 ) / 174471

GCD(311, 561) = 174471 / 174471

GCD(311, 561) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 711

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

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

GCD(1, 711) = 711 / 711

GCD(1, 711) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 175

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

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

GCD(1, 175) = 175 / 175

GCD(1, 175) = 1

GCD of 311, 561, 711, 175 is 1
