Greatest Common Divisior

We found the divisors of 909, 920, 511, 909 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 909, 920, 511, 909 is 1.

Therefore, GCD of numbers 909, 920, 511, 909 is 1

Given Input Data is 909, 920, 511, 909

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

Prime Factorization of 909 is 3 x 3 x 101

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 511 is 7 x 73

Prime Factorization of 909 is 3 x 3 x 101

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(909, 920) = 836280

GCD(909, 920) = ( 909 x 920 ) / 836280

GCD(909, 920) = 836280 / 836280

GCD(909, 920) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 511

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

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

GCD(1, 511) = 511 / 511

GCD(1, 511) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 909

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

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

GCD(1, 909) = 909 / 909

GCD(1, 909) = 1

GCD of 909, 920, 511, 909 is 1
