Given Input Data is 689, 429, 80, 884

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

Prime Factorization of 689 is 13 x 53

Prime Factorization of 429 is 3 x 11 x 13

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 884 is 2 x 2 x 13 x 17

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(689, 429) = 22737

GCD(689, 429) = ( 689 x 429 ) / 22737

GCD(689, 429) = 295581 / 22737

GCD(689, 429) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 80

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

LCM(13, 80) = 1040

GCD(13, 80) = ( 13 x 80 ) / 1040

GCD(13, 80) = 1040 / 1040

GCD(13, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 884

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

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

GCD(1, 884) = 884 / 884

GCD(1, 884) = 1

GCD of 689, 429, 80, 884 is 1
