Therefore, GCD of numbers 459, 731, 263, 646 is 1

Given Input Data is 459, 731, 263, 646

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

Prime Factorization of 459 is 3 x 3 x 3 x 17

Prime Factorization of 731 is 17 x 43

Prime Factorization of 263 is 263

Prime Factorization of 646 is 2 x 17 x 19

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(459, 731) = 19737

GCD(459, 731) = ( 459 x 731 ) / 19737

GCD(459, 731) = 335529 / 19737

GCD(459, 731) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 263

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

LCM(17, 263) = 4471

GCD(17, 263) = ( 17 x 263 ) / 4471

GCD(17, 263) = 4471 / 4471

GCD(17, 263) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 646

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

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

GCD(1, 646) = 646 / 646

GCD(1, 646) = 1

GCD of 459, 731, 263, 646 is 1
