Given Input Data is 890, 665, 260, 266

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

Prime Factorization of 890 is 2 x 5 x 89

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 266 is 2 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(890, 665) = 118370

GCD(890, 665) = ( 890 x 665 ) / 118370

GCD(890, 665) = 591850 / 118370

GCD(890, 665) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 260

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

LCM(5, 260) = 260

GCD(5, 260) = ( 5 x 260 ) / 260

GCD(5, 260) = 1300 / 260

GCD(5, 260) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 266

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

LCM(5, 266) = 1330

GCD(5, 266) = ( 5 x 266 ) / 1330

GCD(5, 266) = 1330 / 1330

GCD(5, 266) = 1

GCD of 890, 665, 260, 266 is 1
