Therefore, GCD of numbers 77, 330, 419, 804 is 1

Given Input Data is 77, 330, 419, 804

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 419 is 419

Prime Factorization of 804 is 2 x 2 x 3 x 67

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(77, 330) = 2310

GCD(77, 330) = ( 77 x 330 ) / 2310

GCD(77, 330) = 25410 / 2310

GCD(77, 330) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 419

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

LCM(11, 419) = 4609

GCD(11, 419) = ( 11 x 419 ) / 4609

GCD(11, 419) = 4609 / 4609

GCD(11, 419) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 804

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

LCM(1, 804) = 804

GCD(1, 804) = ( 1 x 804 ) / 804

GCD(1, 804) = 804 / 804

GCD(1, 804) = 1

GCD of 77, 330, 419, 804 is 1
