Given Input Data is 190, 980, 28, 665

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 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 665 is 5 x 7 x 19

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, 980) = 18620

GCD(190, 980) = ( 190 x 980 ) / 18620

GCD(190, 980) = 186200 / 18620

GCD(190, 980) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 28

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

LCM(10, 28) = 140

GCD(10, 28) = ( 10 x 28 ) / 140

GCD(10, 28) = 280 / 140

GCD(10, 28) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 665

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

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

GCD(2, 665) = 1330 / 1330

GCD(2, 665) = 1

GCD of 190, 980, 28, 665 is 1
