We found the divisors of 404, 821, 650, 305 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 404, 821, 650, 305 is 1.

Therefore, GCD of numbers 404, 821, 650, 305 is 1

Given Input Data is 404, 821, 650, 305

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

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 821 is 821

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 305 is 5 x 61

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(404, 821) = 331684

GCD(404, 821) = ( 404 x 821 ) / 331684

GCD(404, 821) = 331684 / 331684

GCD(404, 821) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 650

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

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

GCD(1, 650) = 650 / 650

GCD(1, 650) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 305

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

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

GCD(1, 305) = 305 / 305

GCD(1, 305) = 1

GCD of 404, 821, 650, 305 is 1
