Given Input Data is 720, 867, 87, 697

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 867 is 3 x 17 x 17

Prime Factorization of 87 is 3 x 29

Prime Factorization of 697 is 17 x 41

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, 867) = 208080

GCD(720, 867) = ( 720 x 867 ) / 208080

GCD(720, 867) = 624240 / 208080

GCD(720, 867) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 87

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

LCM(3, 87) = 87

GCD(3, 87) = ( 3 x 87 ) / 87

GCD(3, 87) = 261 / 87

GCD(3, 87) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 697

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

LCM(3, 697) = 2091

GCD(3, 697) = ( 3 x 697 ) / 2091

GCD(3, 697) = 2091 / 2091

GCD(3, 697) = 1

GCD of 720, 867, 87, 697 is 1
