Given Input Data is 190, 870, 875, 668

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

Prime Factorization of 190 is 2 x 5 x 19

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

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 668 is 2 x 2 x 167

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(190, 870) = 16530

GCD(190, 870) = ( 190 x 870 ) / 16530

GCD(190, 870) = 165300 / 16530

GCD(190, 870) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 875

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

LCM(10, 875) = 1750

GCD(10, 875) = ( 10 x 875 ) / 1750

GCD(10, 875) = 8750 / 1750

GCD(10, 875) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 668

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

LCM(5, 668) = 3340

GCD(5, 668) = ( 5 x 668 ) / 3340

GCD(5, 668) = 3340 / 3340

GCD(5, 668) = 1

GCD of 190, 870, 875, 668 is 1
