Greatest Common Divisior

We found the divisors of 406, 731, 484, 641 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 406, 731, 484, 641 is 1.

Therefore, GCD of numbers 406, 731, 484, 641 is 1

Given Input Data is 406, 731, 484, 641

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

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 731 is 17 x 43

Prime Factorization of 484 is 2 x 2 x 11 x 11

Prime Factorization of 641 is 641

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(406, 731) = 296786

GCD(406, 731) = ( 406 x 731 ) / 296786

GCD(406, 731) = 296786 / 296786

GCD(406, 731) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 484

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

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

GCD(1, 484) = 484 / 484

GCD(1, 484) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 406, 731, 484, 641 is 1
