Given Input Data is 693, 870, 895

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

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 895 is 5 x 179

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(693, 870) = 200970

GCD(693, 870) = ( 693 x 870 ) / 200970

GCD(693, 870) = 602910 / 200970

GCD(693, 870) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 895

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

LCM(3, 895) = 2685

GCD(3, 895) = ( 3 x 895 ) / 2685

GCD(3, 895) = 2685 / 2685

GCD(3, 895) = 1

GCD of 693, 870, 895 is 1
