Therefore, GCD of numbers 406, 819, 992, 460 is 1

Given Input Data is 406, 819, 992, 460

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 819 is 3 x 3 x 7 x 13

Prime Factorization of 992 is 2 x 2 x 2 x 2 x 2 x 31

Prime Factorization of 460 is 2 x 2 x 5 x 23

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, 819) = 47502

GCD(406, 819) = ( 406 x 819 ) / 47502

GCD(406, 819) = 332514 / 47502

GCD(406, 819) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 992

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

LCM(7, 992) = 6944

GCD(7, 992) = ( 7 x 992 ) / 6944

GCD(7, 992) = 6944 / 6944

GCD(7, 992) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 460

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

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

GCD(1, 460) = 460 / 460

GCD(1, 460) = 1

GCD of 406, 819, 992, 460 is 1
