Therefore, GCD of numbers 720, 818, 688, 279 is 1

Given Input Data is 720, 818, 688, 279

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

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime Factorization of 818 is 2 x 409

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

Prime Factorization of 279 is 3 x 3 x 31

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(720, 818) = 294480

GCD(720, 818) = ( 720 x 818 ) / 294480

GCD(720, 818) = 588960 / 294480

GCD(720, 818) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 688

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

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

GCD(2, 688) = 1376 / 688

GCD(2, 688) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 279

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

LCM(2, 279) = 558

GCD(2, 279) = ( 2 x 279 ) / 558

GCD(2, 279) = 558 / 558

GCD(2, 279) = 1

GCD of 720, 818, 688, 279 is 1
