We found the divisors of 803, 404, 698, 455 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 803, 404, 698, 455 is 1.

Therefore, GCD of numbers 803, 404, 698, 455 is 1

Given Input Data is 803, 404, 698, 455

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

Prime Factorization of 803 is 11 x 73

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 698 is 2 x 349

Prime Factorization of 455 is 5 x 7 x 13

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(803, 404) = 324412

GCD(803, 404) = ( 803 x 404 ) / 324412

GCD(803, 404) = 324412 / 324412

GCD(803, 404) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 698

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

LCM(1, 698) = 698

GCD(1, 698) = ( 1 x 698 ) / 698

GCD(1, 698) = 698 / 698

GCD(1, 698) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 455

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

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

GCD(1, 455) = 455 / 455

GCD(1, 455) = 1

GCD of 803, 404, 698, 455 is 1
